Anywhere east of I-35 in Austin, TX, in the five and a half (512 area code). In other words, east Austin, which, of course, is markedly less civilized and affluent than the western half. A good place to get jacked up - as well as str8 up got. Don't drive into this area in a phat ride with heavily tinted glass and gold rims, or some cholo might take a guage to your driver's side window - even at a stop-light.
"Biiiiiiiitch, we're ballin' thru E-to in this bitch-ass Impala we jacked, and nobody gives a shit! Whatuuuuuuuup?!?!"
