Hood has alot of snow and got alot post-March. They'll be good, but the earlier the better...anywhere.
Whistler for sure has a public park, and you can ride the public park, but the camp's stuff is "off limits" but people like to poach it, which happens alot. www.whistlerblackcomb.com
Just look for the public park stuff in there. Or go to Mammoth and buy an MVP pass...
