Glad I don't live in DC. Interesting.
As I stated, on another forum. This amounts to 'user tax' to exercise your constitutional right. Imagine the outcry if such a tax was levied on your ability to practice religion. Remember how the Left always said: 'confiscation' was a scare-tactic' created by the NRA to help solicit donations. I rest my case, and would have you look to Connecticut.
