This is why I never canvas alone (part politics-filter, part nonpartisan word of caution)
→[More:]I never, I mean never, go door to door by myself. And here you see why. There was at least one occasion I can think of offhand, in this cycle, where I thought that I would have been punched if they hadn't seen my buddy waiting for me to catch up at the head of the sidewalk.
And it can be worse than that, too. A good friend's mom was raped when she was going door to door for her union. My friend didn't find out until she told her mother she was canvassing this year, and her mom freaked out and warned her never to go alone.
The most alone I'll ever get is alternating houses with a buddy on the same side of the street. But I still prefer going to the same doors at the same time. Usually just having a second pair of eyes to witness will be enough to keep most of the loonies in check. And god forbid, with the worst of them, there is someone to call for help if the other gets into a situiation.
I know a lot of us are canvassing and such right now, and the idea to split up and cover twice the ground is tempting. It's a serious risk, though. Especially given how heated emotions are on both sides now.
