Welcome to the community Rock. Its great to have more older, mature members joining our community! It really is a great way to relieve stress as well as makes some new contacts if not friends. There really are no legit airsoft only fields down here. We are the only organization recognized by not only the County of West Palm Beach but also in good standing with the State as well.
Our forums are still growing as is the organization (SFAA) We are currently ironing out the details of our field with the county and will be hosting some fundraiser events in the near future to help get the field built. If you would like to get more info about AEGs and other airsoft information (like where we play for now) you are more than welcome to sign up at sead-online.org.
If you would like more info on how you can help with fundraising or donations, you can contact the SFAA staff @ email@example.com
Again, welcome and we look forward to providing you and your friends and family a safe, sanctioned airsoft field. Best of luck to your son and his decision to join our Armed Forces. A very commendable action in this day and age.
We look forward to seeing you out on the field.
