Bring your parents, especially if they play airsoft.
Parental participation is the number #1 golden rule for minors and airsoft. You are likely to get a lot further if your parents are right by your side. A lot of people, like myself, have nothing but complete respect for parents that introduce their kids to airsoft in a responsible manner.
Seriously, I really don't understand why kids aren't embracing the idea like hot cakes. I'd have loved to play airsoft with my old man, had I been given the chance earlier in life.
