I've often wondered why shops don't buy and use one of those practice shock absorber type doo-hickies that allow you to draw and fire a bow without an arrow, like the one talked about in "idiot proof archery".
How many you gonna buy???
Do you want to run around swapping it on and off 10 bows as 3 guys look at them.......LOL
When I get my range I will most likely have an arrow in the bow policy - but for now - I must take the lumps.
