I've been through Bastrop kilted a couple times, no problems. I know it's "in the country" but I don't really think of Bastrop as a rural community any more, it's been pretty well messed up by the yuppie overflow from Austin IMO.

Anyway, Austin is the place for a little nightlife, in addition to the places already mentioned, you might look into Coyote Ugly on 6th street, they love the kilt;
