rule number 2:
dont do stupid stuff!
A carbon arrow shot into the air takes a long time to come down.
Backstop netting doesnt stop arrows.
Hedges dont stop arrows either.
It frightens me the number of people (some very experienced archers) who practise in their own gardens. When you ask "how long is your garden?" the answer is often "if I put the boss right against the neighbours fence I can get 18m in if I stand against my house wall!"
Ask for trouble and you often get what you ask for
