On they way up from Allentown, what's the last area where a grocery store would be located?

There is a dollar general store in town that's about 25 minute drive or there is a local store about 5 minutes away that sells camping stuff

There is also a Dollar General located on Rt 6 that sells groceries close to town.

Campfire wood and other camping needs can be purchased from a nearby store less than 5 minutes from the star gazing site
