welcome back to the sport. My names james. im one of two site locals to the Nam field. So if you wanting to get in some shoot time and brush back up on your skills, let me now, and i can arrange for the local town team up here by the nam fields to come out and we can all have a training day. The Nam field is also a good place to re hone your skills because a lot of(not all) of the outdoor games are held there. As for you battery problem, theres AEX in rancho cordova, and i believe(not 100% sure about this) an airsoft store in grass valley depending on what would be closer to your location. hope ive been of some help. And if your interested in training let me know through pm on here. i check this site at least once a day sometimes more. Again welcome back to the sport, and welcome to our "happy" family of a site.
Play, shoot, laugh, enjoy the game.
