austin is super bike friendly...the most bike friendly city in tx.
it's also one of the (if not the top) top cities for bike theft in the US....so that sucks.
good bar scene, lots of music clubs, tattooers, great food (stubb's, chili parlour...), outside the city is amazing...(perdernales, bee cave, marble falls etc...), lots of riding elevation, also.
check out john prolly's strava......you'll get a good idea of the riding there.
pretty mild weather, too.
