Is that the one off university avenue where 68 and 79 meet or the one at university town center on the star city exit of 79? If you want to meet at a Walmart in Morgantown, if memory serves there is not much else at the university avenue Walmart. The one at Star city/ university town center has a lot more stuff. Several restaurants of various flavors. It's a couple exits up the road from the 79/68 junction. The other options would be to meet in Fairmont or Clarksburg. Just down the road (79) from there. I can recommend food about anywhere around there. In south Fairmont you have a mall that's pretty defunct but they have several restaraunts (Italian, Chinese buffet, pretty good Mexican place, bob Evans, applebees and assorted fast food). There's an ace hardware in the mall and a Sears home store. Walmart is more or less across the road too.
If you want to go all the way to clarksburg, there is about anything you can imagine off the Annmore exit of 79. Food. Stores. Whatever your heart desires pretty much.
On that route, there's not much else. There's an out let mall at exit 67 flatwoods. Then it's pretty much nothing till you get to charleston. I recommend trying to time it so you need fuel in Ashland Ky. It's just across the border on the other side of Huntington. Fuel used to be cheaper in KY, I assume it still is. There's a flying J there. I think they put another something in there too later.
Anyway, if there's anything you want to know about that route, let me know, I've driven all of it.... a lot. It's been a while since I did the Morgantown to Ky trip but I'm sure it hasn't changed that much.
