When I met with my rep he was not planning on trying to lead a charge for unlicensed carry, but he indicated that he was genuinely making an effort to be open-minded about it.
The bill needs to be solid and refined, though. Unlicensed carry is going to "touch" a lot of "peripheral" issues and if those issues aren't considered and worked out by the bill authors, it'll leave too many holes for criticism or amendments which could either prevent passage or allow butchering.
So far I'm unaware of who or what teams are actually working on this process of refining a good unlicensed carry bill. I hope to find out and talk to them, though.
Another concern is that currently, well, our statutes are a mess. As I have happened into situations where I look at other state's statutes, it seems to be a common trend to have really messy and convoluted statutes, but, I think it'd behoove us to focus on cleanup. As laws have changed, and been modified, and gutted, or added to, we have ended up with pieces, and remnants, that contradict, or make issues ambiguous, and that can only hurt us I think. I would hate for us to put a lot of effort into passing an unlicensed carry bill, and then some orphaned little remnant of a statute somewhere give a bad judge leeway to try and undermine the new law.
