As a follow-up, we did two rides:
Mountain Station pedal: climbed up Badger, Honey, Shasta etc. and rode Skirt, Fat Chance, Tiger Buckle/Five Knuckle, Legalize It. Awesome trails, nice steep fall line tech with well built jumps and drops. Surprised some of the stuff was rated blue, could be a rude awakening even for people used to Sea to Sky blues.
Powerslave shuttle: got dropped at the lower entrance to lower part of Powerslave, shuttle guy said upper wasn't worth the ride but I think next time we would go for it anyway. Bottom part of Powerslave and Bear's Den outstanding trails, more fall line tech with fun doubles, option lines and cool wood work on Bear's Den. Pedaled up Toughnut which was a grindy climb that mellowed higher up. Got confused by a new logging road and missed Upper Goldmember, jumped into Lucky Charms and Gold Rush, fun more rocky trails and then into Waldorfian which was awesome steep tech, highly recommended.
Nelson is amazing, so glad I got to finally ride there. Will be back every summer for sure.
