that is good how early can you shred it?
Well that depends. Riding up to it will generally be dry but the actual bobsled can have wet spots.
You might be good to go the weekend after next.
I personally not much of a DH person but love the whole deal up/down and flats. Park City has a lot of single track riding. You could also hit the south mountain trails by draper. they are pretty good too.
Utahmountainbiking.com has good info. Supposed to be family forum and words are but theres attitude pretty much like every other mtb forum ive visited.
Have fun with it.
