Hey, the security cameras are a really good idea!
And I agree, it is probably nothing. I guess what rattled me was it's cramped, odd location, and how I have never seen that particular mark before.
I also have been involved with more crime these past eleven months than in my whole life combined (where I work was robbed in March, and the dudes returned to scope the place out again last month, my bus stop was swarmed by thugs that attempted to rob several us at once -unsuccessfully- in July, and these are just a few things that come to mind quickly), so I am always on high alert while trying to not stand out too much.
Having pepper spray is something I am ok with.
Again, I like the camera idea. I think that this has pushed me to reevaluate our front gate's security, in case I do see a mark that I can pinpoint as dangerous without a doubt.
We are in an ok neighborhood in the province, and the house is pretty nice...but I don't own it, and worry I look like some wealthy foreigner/easy target, when in fact I don't have much.
