May long is very doable on Boulder, i can't see anyone doing Frisby. Just make sure you take Kirkup and not Vied or Bez, you will be riding creeks and rocks like no other. Best if you have a truck and deck with you that has some big rubber and lifted to bust through some spots with snow on some of the corners but then it's bare again. Last time i did it was 2005, we parked at the long 90 degree corner after the straight section and front side turtle turn off. There was about a foot or so of snow on the corner so couldn't go any further, but as soon as we made it around the corner it was totally bare, never hit really good solid continuous snow till we were close to the Y intersection for Bez and Kirk. Best guess is you have to drive around 10k's but that's just a guess.

Cheers
