Hmm... tomorrow I'm planning on taking the dogs to Hillsdale State Park so we can go swimming in the lake there and I'll take a look around there for some mulberries, now you've got me wanting to make some homemade jam too!
Also, Olathe is actually not that bad for travellers, I went through here in the summertime last year, cops don't really care as long as you're polite to them. I wouldn't recommend going through Overland Park to anybody though, they're pretty strict on anti pitbull laws. I guess what I'm trying to say is, travelling through the KC area, it's probably best to just stick to KC.
