Just an update.
I now know of about 8 break-ins. There have been my 2, 2 on Sutherland and 4 on Guthrie.
If anyone lives up that way, I have also noticed an older red pickup (Ford I think) slowly cruising the area. It has stopped in front of our house a couple of times. Maybe I'm paranoid, but I never saw it before this rash of B & E's.
