I'll echo the words a few have written. Find a place to shoot with friends!
Next, visit Binghams project web site and order the plans for two bows, one for you and the other for your son. Then plan it all out together, this will create a time for the both of you to talk, make plans for future hunts and dream. In the end, the time you will have spent with him making those two bows, will live in him forever! And in the end, you both have two brand new bows! I hope you both find it again, it is there!
