I don't know of any alleys in my area (Seattle, Washington, USA) where the buildings are close enough together to allow someone to do any "bridging" or "chimneying." But every now and then….

I live only a few blocks from Volunteer Park, which features a large brick watertower near the South entrance. One day after work, I drove through the park, observed the antics of the people, squirrels, crows, then drove out the south end to head home. As I neared the watertower CLICKY, I spotted some guy more than halfway to the top, splayed out like Spiderman and groping with one hand for another handhold….

Oy!!
