I finished an epic game against Yog-Sothoth yesterday during which one of my investigators became the Deputy of Arkham. I was playing with the Dunwich Horror Expansion, so three questions occured to me (two of which aren't really related to Dunwich, but anyway).
1. Is it possible to use the Patrol Car to travel between towns in an instant?
2. If you lose the Patrol Car, is there any way to get it back?
3. I don't really get the text on the card for the Deputy's Revolver (as well as the text on cards like the Deringer or the Magic Stick). It says that the revolver can not be lost or stolen unless you choose to. But at the end of the day, isn't it the same for all other items as well? When you lose an item, you are the one who chooses which one, so unless you choose to lose a perticular item, you won't. The only two exceptions I could think of would be the final battle against Ithaqua where you have to roll a die for every item you carry, or when you would lose an item, but don't carry anything except for the Deputy's Revolver. Am I missing something?
Thanks for the answers in advance 
I was like "Well, if you lose your stuff it's rounded down, so if you have the Derringer as a single item, you could never lose it as well"... Didn't think about having two of those items at the same time, but that sounds pretty plausible. Thanks for the answers.
