For that reason I believe that I can do this to a recognizable degree of accurcay (I'm hoping to be within 2,000 miles of the correct answer). Either way, it will still be a nice experiment to do and I'll definitely report back on how it went.
Good luck!
Please also post your findings to The Flat Earth Society

Well good luck with the experiment.

Yes, please report back, either way, what your findings are.

Isn't this an old topic? I remember this or something very similar.

The laws in Denver I'm sure are the same as any other local or state laws. Don't harass anyone and you'll be fine. Find away to terminate the beam at the other end.

Would Standley Lake be an option? Looks to me the surrounding area has little population

Yeah, this has been brought up before. Except that guy came out and said that it was for a FE theory experiment. And got a lot of crap for it.
