A word of warning. The state can be pretty lax about registering an out of state car, but the towns are a different matter. Many of them ride around with license plate scanners. If they notice the same out of state plates around for long enough, they might start to threaten you with tax bills. If you park anywhere outdoors, be especially careful of this. People have had trouble for visiting out of state family for a couple weeks. It is all very "guilty until proven innocent", so for people who really haven't moved, it can be a nighmare.

High speed rail with a few stops in big population centers only works if you can reach it. If the choice is gentrification and huge parking lots, then it is missing out on serving a lot of people. CT needs a better last mile. We have so many old rail lines that would make great light rail or rapid bus corridors to even out density without causing sprawl.
