Since we moved to this part of the city, none of us have been riding as much. We're farther from many things, and there's a lot of busy roads.
So we put our bikes on a screened in front porch. There's a large banana tree and bushes in front of it so you wouldn't see the bikes unless you came in or were walking towards the door (on the side), on the side walk.
My roommate has been talking about building a rack or mounting something to the floor to secure our bikes to, but he's doing school, and working full time and so it wasn't top on his list of things to do.
My g/f goes to leave and she said her bike was gone, and that she's noticed our roomie's hasn't been around either, but she thought he lent it out to somebody and it never crossed her mind to bring it up when she saw him.
Her bike was there when we came in, so somebody literally snuck onto the porch while we were there eating and swiped it. The porch door was left open, too.
So they actually came back twice.
At this point, I believe the grand or so is totally worth the loss of their lives, by means of bullet to the head.
