We've been riding in the snow, the horses are frisky, ~the Ice is a little trickier~
Bareback will keep you warm for a while (unless your horse sweats), long-johns are a must....... wear warm socks tho, cause your toe-sey's will get cold after a while (about 2 1/2 hours and I was done).
OH yeah lots of coffee or hot cocoa before and after!!!!!!
