Had a nice meeting with RedCowBoy in GA.

Recently had the opportunity to meet RedCowBoy and his dad for dinner in Georgia near Atlanta, was a pleasure. Great guy and his dad too, we had something in common as his dad also worked for AT&T in the past as I had.

RedCowBoy gave me some good advice and information on this forum and seems like a good guy. What work did you do for AT&T? I was wondering because I am interested in the field of electronics and thinking about careers.

Alaskan is a good guy, he should think about changing his name to Georgian.

Re: Had a nice meeting with RedCowBoy in GA.

My wife was with us too and there is less of a cow in the world now, we all had steaks at a Longhorn steak house.

Leaving Georgia tomorrow, going to a Army base in Texas next, my wife back to Alaska and in a week, I'm supposed to be in Afghanistan. Georgia is very nice, only one complaint to vent heavily; sneaky, obnoxoius, passive-aggresive drivers abound here, too many unkind me-first screw you automobiles on these roads. That isn't so unusual I suppose, but I've never seen drivers take so many risks cutting eachother off so much anywhere before.

Other than that, Georgia is verrrrry nice and the people unusually friendly (except driving). Atlanta is awesome, might end up living here someday. So many houses and businesses have nice buildings compared to Anchorage and it is wonderfully green down here. My wife has never liked Anchorage very much due to the lack of nice big green trees and a city of only 370K population, she is used to Odessa, Ukraine with millions.

To answer a question, I did satellite telecom for AT&T as a technician, but the company isn't what it used to be. Actually, AT&T bought the company I was working for, that's how I ended up with them but union wages staggnated for 10 years after that, so I left.

Re: Had a nice meeting with RedCowBoy in GA.

Who picked up the bill?
I don't know if you had previously spoken much personally off the forum but did you see the avatars different from the person. I have a couple very good phone call friendships from members here and at first contact it was a little off the avatars.
I doesn't seem though that there was enough time to spend at i'm guessing RedC house and play lasers
@Alaskan when I first moved to Fall River MA from the Boston area I saw the exact same driver mentality and it pisses me of something furious, the worst thing though its mostly the female drivers.

Re: Had a nice meeting with RedCowBoy in GA.

I pretended my credit card didn't work and stuck RCB with the whole bill and tip to boot Kidding though, I asked him to dinner so twisted his arm and wouldn't let the check go to them but they tipped, all I would let him do, ha ha...

In RCB's case I didn't see any different than earlier impressions except his humorous witt is more pronounced in person. We started to rant about Obama some, but his dad cooled our jets on that so the dinner didn't turn into a gripe session

Didn't end up at his house, we picked a meeting place mid-way from eachother.

Re: Had a nice meeting with RedCowBoy in GA.

Great thread guys, so good to hear you guys meeting up, sounds like it was a great evening.
I love reading about all these destinations, would love to visit these places one day but it's not easy to get away ....
Looks like you guys will have to visit downunder instead.

“He who believes in Him is not condemned;

And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”

Going to El Paso. Always wanted to go downunder there to Aussieland, would work there if I could find a job.

Hey, if you're looking for a place to relocate that has nice drivers, consider Denver. I'm always pleasantly surprised when we travel south into Colorado and get into big traffic snarls in Denver. Nearly any time you want to change lanes just turn your signal on and someone behind you in the lane you're trying to get into will slow up and leave a gap so you can make the change you're signalling with no hassle. Most other areas I've traveled to it seems like the traffic just gets tighter when someone sees that you're trying to make a change.

In Wyoming we don't have major traffic snarls so the politeness of the drivers isn't tested so much. We haven't been that Californicated yet.
