I was just looking at pics from last year. It was this weekend last year that I went road ridding and broke in the sled. That was in 18-24". The following weekend was full on back country riding in about 36-48".
The bummer part is that this year actually started even earlier. was dumping snow in mid October and then it all went to crap! Grand Targhee has seen 60" of snow fall already, but everything below about 9,000ft has melted off. Eric
