In Florida you can have loaded gun, holstered (not on your person), in your vehicle. No permit needed.
In Maryland, thanks to O'Malley, you can't have a gun AT ALL, unless it is on an approved list, you pay a fee of over $100 and apply to the state government to own it.
However, this has done nothing to decrease gun crimes in Maryland. But it has done wonders in decreasing gun ownership among the population of law-abiding citizens.
Even then, getting a carry permit in Maryland is almost impossible. I was told not to even bother trying since I do not have "proof of a clear and imminent threat to . . . (my) life".
Further, from the State Police website, "There are further regulations but essentially you can only transport a handgun between residence, to and from a repair shop, a shooting sporting event, between a residence and place of business if substantially owned and operated by the person." In other words, Maryland is an anti-freedom hellhole. Sadly, I have family reasons that prevent me from moving.
