You guys out in PA have been 2-3 days behind us in MI this season for weather. Most resorts open now are boasting 24-40" base or more, that ain't going anywhere in one or two days of warm weather.
Riding in those temps can be a mixed bag sometimes it's slushy and fun sometimes it's like riding on a wet carpet and it sucks. I'm hoping it's fun... got plans to meet up with some forum friends on Saturday.
I once went snowboarding in Michigan and it was 84 degrees. So, it's certainly possible!
