deer valley IS for rich people that like groomers. that means, however, that the snow off the trails doesn't get touched. at least not very quickly.
dv is super expensive so i don't go there unless i wind up with a free ticket for some reason, but if your parents are paying, it could be a lot of fun. they have some sick cornices (with perfect wide-open inruns too!) and good tree skiing.
but if it's park you want, go to pc.
