Is it so bad in Texas that you can't even buy wine at a privately owned shop???
Texas is actually fairly reasonable with its liquor laws. The state stays out of selling booze except for taxing. Blue laws close the liquor stores at 9:00pm and all day Sunday, but you can get wine and beer at grocery stores and convenience stores until midnight during the week (staring Sunday) and until one on the weekends.
The greatest liquor store that I've ever been to is in Houston (Specs downtown).
Pennsylvania is comparatively backwards. The state sells all the beer and wine (although they are open on Sunday). Beer is an even more bizarre situation. Retail, it can only be purchased from so-called beer distributors and then only by the case (24). You can go to a bar and get a "sick pack to go" but then you pay close to bar bottle prices and the selection is generally poor.
It makes buying wine here a very different experience. The good news is that all inventory is searchable on-line. The bad news is that you can't really get employees to recommend anything. So you do all your research at home and then just show up to pick up the bottles.
On topic, I should say that I've been enjoying most Renwood Zins and especially the 05 Old Vine.
