Austin is a great city!!! The South Congress Ave area has great clubs and of course, Sixth Street. I love to walk around the Capitol and you can check out the Texas History Museum.
I think that you will find Austin is a great and prgressive community and it's a lovely place to hang out. The lakes are gorgoeus! Since I am of an older age, I'll have my DD post here with some great clubs and music venues to check out.
Oh, and you will have no problems meeting up with other gays in Austin. There are lots of good looking Texas men, gay and straight. lol
