UPDATE:

As part of the initial invitation, my son's friend had agreed to join us for a work day at the lease on Saturday, 11/30/19. My son called his friends on Friday, 11/29/19, to confirm the time that we were planning to pick him up and he replied that he was busy and wouldn't be able to make it. My son told him that the work day wasn't optional and that he wouldn't be invited back if he didn't do the work that he'd agreed to.

My son was pretty pissed that after we'd provided all of the hunting kit, bought the tags, paid for the processing last year and the taxidermy fees to have the buck that he shot last year mounted, that his friend wasn't going to follow through and do what he'd agreed to do. I told my son that it was a good life lesson for both of them.
