At least we are getting plenty of warning that something very bad is coming. That wasn't the case with Maura's big surprise. You are very lucky to have been able to do a last minute grab on 7/20/2016. The 2 shops I had made plans to visit that very day had both gone into total freeze mode by the time I got there.
In regard to grandfathering, I don't think that our lefty DimocRAT pols "know it is required." I don't think they think of it that way at all. Someone with a brain will have to give them the factual pros and cons (I hope it is GOAL and not BloomingTurd & Giffords). They would love to have all of us completely disarmed, but they may decide that is a bridge too far for this current legislation.
On this we are in full agreement.
Buy now everyone... or wish you had later.
