For the record, I did find two places in Wolfeboro that have nice, humidified humidors. They're standalone, next to the registers, but I tried cigars from both and they were both passable (and saved me a drive to Dover or Laconia!):
1) The Wolfeboro Corner Store @ 148 S. Main St, Wolfeboro, NH 03894

2) B's Express Mart @ 35 Center St, Wolfeboro, NH 03894

Enjoy :-)
