TRIGO is a (dis)organization of geocaching enthusiasts in southwestern Pennsylvania. We’re not sure what TRIGO stands for but we think that it could be an acronym for Three Rivers Informal Geocaching Organization or something like that. The purpose of this group is to coordinate events and promote geocaching in our area. There are no dues or anything like that because we want to keep this club free and fun. [attack against other organizations removed by mod] TRIGO does not exclude anybody or their opinions from our forum. Anyone interested in geocaching in SWPA can join us in our disorganization.
