RE: how do I find my arrows??
Walking barefoot is a great tip to help find them. As for not loosing them in the first place, Don't shoot toward tall grass. Where I shoot I have 20-30 yards of mowed lawn behind the target. If the grass isn't knee high it shouldn't be too hard to find.
One other thing that may work if the ground is wet is to stretch out your finger tips and push them into the ground. If you were shooting North to South work your fingers in an East West direction. It is time consuming but should result in found arrows.
