Texas:
$40 for an ounce of corn (texas talk for decent stuff)
$70-80 for ounce of regular stuff
$120 for an ounce of dro
$560-700 for an ounce of primo exotic (seriously one-hitter quitter quality!:jointsmile

I think it's because there is so much land to grow here. You can get the dro in some of the larger cities (50,000+ population) but if you want the primo you have to go to the big cities (250,000+, Dallas etc.)
