I love WalMart, you can get all kinds of stuff, sometimes even stuf you want or need, all at three in the morning. Like right now, right this minute if my wife woke up and told me I needed to go and get some red skin potatoes or a box of half penny nails I could drive over there and get them. The downside is that I would have to deal with a bunch of zombies who couldn't find thier asses with both hands behind thier back, but at least I could get my stuf, and it would be cheap, hell even McDonalds charges extra for staying open late.
Trust me, Wal Mart is a great place, I once found my self in the middle of nowhere working outside at cell towers in the middle of the night when both of my Halogen worklights had bad bulbs at once, I promise you your average truckstop and filling station does not have 500W halogen bulbs, but Wal Mart does, they are cheaper than anywhere else to.
