I haven't picked one of these up yet...but you know I will.

Austin Star Map offers complete detailed walking and driving directions for celebrity homes, filming locations, favorite restaurants and hangouts.
The first time I visited Austin, I demanded my friend take me to the Tarrytown house where MM was busted with bongos. I can't for the life of me locate it now. Luckily, it's on the map!
So are other homes of almost every celeb who has ever lived in Austin as well as filming locations for
Dazed and Confused, Office Space, Varsity Blues, Miss Congeniatlity and more.
HERE's a link to the site where you can find out more about the map.
And
HERE's a link to the page where they list local celeb sightings.
Maybe I can be a contributor!
