Shed construction, lawn care, model trains, automotive, infants, skydiving.... You name it. Search and you will find.

I tell people you can find anything you are interested in if you search long and hard enough on the internet. My uncle tried for years to find out what these weird, hard, grassy globs were that kept washing up by his beach house. I found out in 20 minutes of digging on the internet that they were basically whale hairballs (but vegatable balls).
