RV is at a friend's house. College buddy, best man at our wedding!
The other RV options are Fort Getty in Jamestown, Paradise and Meadowlark in Middletown, and Melville up in Portsmouth, or Fisherman's over in Narragansett. Middletown and Jamestown are closest, but often sold out well in advance (especially Fort Getty). Of course, there's always WalMart; but I don't think they are letting RVs on-site (even for day parking) at Fort Adams. They never allow overnight camping there, either.
"Experience of a lifetime" is certainly a understatement. I think the reality of it just hit me about a week ago.
