Thanks for the Epoxy suggestion, but I really liked Coach13's recommendation. Will get some in there this evening.
It was a wierd collision. I was comming down Hogsback and Pistol to Gunbarrel at Heavenly. You have to cross the intermediate Round-A-Bout cat-track on the desent. I stopped above the drop-off onto the track and waited for traffic to clear, then hopped down facing uphill. A boarder 50 yards up the trail looked staight at me and turned directly for me and never turned again. There was no place to go to get out of the way as I was pinned aginst the high wall of the track. I caught him in a bear hug, but got blown out of both skis still standing. No one was hurt and he quickly departed. I didn't notice the cut in the skis and the missing top cover to the binding toe-piece until I got to the bottom. Marker replaced the cover no charge, so I just have to deel with the cut top.
Next time I guess I should do a gap jump
