i lost two discs in the tree above 16s basket! one was my drive and one i threw up there trying to get it out, like a moron, and it stuck too! one was a Z wildcat and one was a Z wasp, both bright orange.
well hopefully for his sake there still up there sucks losing a disc and having people try to sell them back to you out of there truck lol. if it was me i would of tried to throw a stick up there to knock them loose.
Try shaking the tree if its small enough. Or wait for a windy day, they might drop out on thier own. I would suggest NOT climbing the tree, like I have done and hurt myself many times. It just aint worth it, if you think about it.
