There's nothing ot be nervous about. I'm a big guy and OC is really all thats comfortable for me. I go everywhere without concern. The bank on occasion, grocery shopping, gas stations, the outback, olive garden, etc. Dress presentable, behave like you aren't doing anything wrong and nobody is going to say anything. I was at the Hopkinton and Deerfield fairs this year sitting watching horse pulls and tractor pulls with children everywhere any nobody said anything or looked the least bit concerned. I really do believe trouble will find you if your looking for it but if your not, you wont have anything to worry about.
Just stay the hell out of federal buildings, schools, court ROOMS (not court buildings) and THE POST OFFICE. All off limits. Enjoy your freedom and dont be scared exercise your RIGHTS. Self-defense is rooted deeply in NH and our current legislature is making sure there aren't any loopholes to convict those who are forced to do so. We live in an amazing state. Stand tall, be proud and dont be affraid to OC .
