Thanks, guys. I saved all my gas receipts if I ever wanted to get into the Ironbutt club officially. That and CC records of when I checked into my hotel (as well as my receipts for dinner in Scottsdale) should be enough. My GPS coordinates, along with time-stamps--are also on my iPhone pics.
But I just wanted to do it to see if I could. I've got the documentation just in case anyone wanted to call BS and claim it was impossible.
Struggling on a slow internet connection--can't even upload pictures. Tomorrow eve I head off to Death Valley, which should be even worse.
As for Austin recommendations--PM me if you don't have a place to stay. Place I was at rocked.
Uchi (Tako Pops, make a reservation)
Tacodeli (Cowboy Tacos, breakfast tacos)
Second Bar and Kitchen (downtown) Get the Chorizo / Avo appetizer
There's a few clubs / bars downtown that I went to--all were cool, but I have no idea what any of them were called
Bats @ the Congress Bridge (show up around dusk)
There's lots to do/see on Congress, too!
