Wonderful ideas, No one, and I especially loved the idea of setting up a huge suffed plastic bag as a target in his back yard. And it wouldn't be for hunting, only accuracy practice so guess a target bow would be perfect. (This child doesn't deliberately stop on bugs either

).
The only local place I could find selling bows, etc is a department store and suspect they will know little of fitting it to his arm length etc. Because I suspect it may be a passing phase (how sure can one be with a 10 year old - grin), I'm off to read all the info at the links you were kind enough to add and then search for the nearest archery club and just cross my fingers it's not an hour or more away - ugh.
Really do appreciate all the wonderful tips and am beginning to wonder if I should ask Santa for a similar gift - huge gentle smile.
