Westboro is just looking to provoke someone or some group into doing something that they can then sue for. They've figured out it's much more effective than a bake sale as a fundraiser. So, don't do anything stupid while these morons are spreading their vitriol.

In the summer for biking, I don't think it would be as large of a difference. I bet it'd be a strong draw for people looking for an easily accessible mountain biking area.
