The Llewellyn Pumpkin Patch
Every fall, the Llewellyn Foundation sets up a pumpkin patch to raise money for Llewellyn school, which by happy coincidence happens to be the school that the bears attend. For the past three years, the best has been part of the foundation, and does some of the work for the pumpkin patch. My contributions are fairly minimal; they use the lemonade stand I built for the bears as their sales booth, and I hover around for the afternoon making sure the bears don't light themselves on fire.
It's a pretty boring afternoon for me, but the bears love it; they spend 4 hours charging around with their friends and can only be pried away when their friends have been dragged away, one by one, by their parents.
