We left Missouri and headed to Benson, AZ the last week in September 2011. We volunteered at Kartchner Caverns AZ State Park. There we helped give tours of the caves. We met several other volunteers there. Some we still stay in touch with to this day. We spent Thanksgiving and Christmas at this park. Our Thanksgiving potluck there included 60 volunteers. This facility has more volunteers then any other place we've been. We loved it.
