On Sunday I went into a hobby store and started leafing through the catalogues of model train cars. A friendly shopgeek passed by and asked if I needed help. I said, "I need a picture of an 1870's cattle car because I'm going to have some people take shelter in it during a vampire attack, and I need to know where the access points are for logistical reasons."
I love geeks. He didn't even bat an eyelash. He pulled out another catalogue and helped me look, while we debated the merits of silver vs. wooden stakes and garlic. He said, "It's always nice to help somebody with an interesting project."
