Lucky! There's no one in our neighborhood with whom to play D&D. I'm jealous.
Whiiiine!
Okay, now that that's out of my system: you are VERY smart to take your own snacks. If you host games at your place sometimes, maybe you can encourage something healthier than Pepsi and chips for other folks, too. I used to feed people fruit and cheese with wine; it seemed to suit the game's atmosphere better than crinkly Dorito bags and fizzy stuff.
Good luck, and I hope you have a blast! Please know that somewhere in New Orleans, someone is desperately jealous of you and your within-driving-range gaming friends. :sniffle, sob!:
