I was taking a picture of a street lamp area in a park after dusk, and a guy comes up and asks what kind of camera i have. I say: "Ahhh... its just an old Pentax", as i'm standing there with my K5, DA-35 and nice tripod, thinking this might be a good place to get mugged
. He was jittery and nervous like he was coming down from some sort of high. He said something about cameras, then asked me for a cigarette, which was pointless as i don't smoke. Then a couple walks up and he gets a cigarette from them. meanwhile i'm packiing up my stuff and heading back to my car before the couple leaves.
There are times when you really don't want to be carrying a large investment in well known equipment
