Parked my rig at Mercy in OKC when my brother was there, used by his kids from out of state. Mercy is next to Oklahoma Heart Hospital, where my brother was, but the sites were still available.
Parked it again at Baptist in OKC when our pastor was there, used by his family.
Parking is free at both sites.
Didn't intend for these to be used for general RV parking - only for those with friends/family in the hospital.
On another note, I found out last year that an Israeli couple was visiting the states and would be passing through this area, so I offered my hookups. They spent five very enjoyable days with us.
