I dress up as a witch for my commute. I have a witch hat that I tie to my helmet. You have to lightly stuff it with newspaper to help hold its shape. I do the broom thing as well. I have never gotten as much attention on my bike than when I'm dressed up. People actually see me! My evening commute is during the start of trick or treat time so I'm home long before the drunks are coming home from the parties. I have to keep an eye out for the kiddies though. Although with all my lights they see me coming and stop and stare. Daughter is going to join me for tomorrows commute. We are going shopping tonight to see if we can find something to decorate my BOB trailer, on sale. I have few ideas. Pictures will be posted if we figure it all out. bikerHen
