If you choose to live in RI over NH, you're a moron. All I want to do is leave RI and this time next year, I will do that. I'm only staying now because I need to get some more work experience on my resume and I would like to buy a used pickup truck and once that's accomplished, I'ma GTFO.
The gun laws themselves aren't as bad as Mass, but that's not saying much. CCW in RI is a cumbersome, clunky process that's not a guarantee. Buying guns without a CCW will be an 8 day wait for background checks, plus you get to pay a sales tax... don't have any of that shit in NH.
If you move to RI, you'll get to wait in line at the DMV, which is a 2 to 4 hour wait depending where you go. Why? Because the DMV is a f*cked up mess. If you move to RI, you'll also get to drive on the worst roads in the country, your vote will be pointless waste, but the people are generally nice, but the people in New Hampshire are nicer.
It depends on what your interests are outside of guns and working. If you like restaurants, entertainment, and such, RI is the better place. If you like the quiet, simple life, the woods, not being taxed, New Hampshire is the place to be. I lived in NH for about 2 months a few years ago. It's nice, but there's not many places hiring people. Not a problem for you tho, so if you can live anywhere you want and work from home, I cannot think of a better place than NH and a worse place than RI.
