Trimming Maple Branches

The Saturday before our trip, we were working in the yard and decided to trim the maple branches that hang down in the next door neighbor's yard. See if you can spot anything important in the picture that I missed:

We set up a ladder under the branches and had the pruning shears ready, I climbed up there and pulled the branch down and hit myself in the back of the head with a huge hornet's nest. It made the hornets very angry. I jumped down, stumbled, and splatted flat on the ground, then jumped up again and flailed my arms around, running and yelling like an idiot. I had to get the hose and hose myself off before I got them out of my hair and shirt collar.
