The one time I went there I parked out at Beaver Creek, about 30 miles east as I recall. But you can park much much closer..
The place is your basic mad house, if you have ever been to a swap and shop multiply b 100 (if it was a big one) to 1,000 (Small one) and you will be darn close. But it is a ton of fun, and well worth the trip.
In 2006 I did the upgrade to General Class (paper upgrade, I was Tech + so I'd passed all the tests) and got my TS-2000 and a few other goodies.
I plan on going back likely in 2014, More for the fun of it than anything.
In addition you have forums and discussions and presentations, You have licensine exams. You have dinners and such "After hours" at various hotels in the area with assoted groups of hams and so much more I can't describe it all.
If you watch either ham nation (
