And Tarrant county is right next to Dallas county.
I'm not sure exactly what the laws are in Dallas, but I think alot of it depends on the officer.
I've been to a party in Dallas, where some people were doing bong hits on the front porch with at least an ounce in plain site when a cop walked up, and all he said is, "you need to put that away and keep the noise down".

LIFE IS SHORT.
DON'T BE A DICK.
