The last time I put a razor to my face was June, 1969, the day I graduated from highschool. My beard has been at least as long as in this pic since. I'm a bit more rigid in this pic than my normal shooting style because I'm showing a full draw pic of the selfbow I'm holding.
When I shot a compound, way back when, I had to wear a bandana to keep my beard out or the string. If not it would look like an extra string silencer on the string.
Since I started shooting trad it has never been a problem. I don't even think about my beard when I'm shooting.
