Old Skis - What to do with them?

I have three pairs of old skis with dated bindings - any advice? I called Willis and they said it won't be worth it to change out the bindings, for that's what I would need to do. I just wanted to see if anyone else has journeyed this path. Also, if it's not worth it - is there an organization, individual, etc, that will take them as a donation vs. sending them to the trash pile? Cheers! Sofia
