I'm going with Andy on this one in regards to the terrain rating . . . I figure most sane people do most of their caching in the summer, spring or fall . . . and yes I am kidding. As such, they would need specialized equipment . . . i.e. some type of boat . . . I consider specialized equipment anything an average geocacher would not normally pack along for a geocaching attempt (i.e. most geocachers would pack a GPSr, batteries, boots, their car has a spare tire, etc.) . . . but most don't routinely haul around a kayak (and some would have to borrow one if they do not own one themselves), bring along climbing rope, ice crampons, diving equipment, spelunking gear, etc.
