Thanks TiggerInLBV,
That is on our "to do list." DS just saw the picture of the fire pit and asked about the marshmallows, so I did the logical thing and passed his question on to the great people of the DIS.
Anyway, we plan on taking my parents over to Fort Wildernes for the campfire and to check out the place where we stayed back in 1972. This will be their first trip back since then.
