I forgot to mention that we have been completely awash in bikers all weekend, because of this thing. It's kind of fun having them around, on the whole - they're certainly more colorful than your average tourist - but my god are they noisy. Since I don't have a functioning air conditioner in my car I generally drive around with the windows open, and I thought they were gonna split my eardrums a couple of times. I gather making your engine quieter is not a big priority with the Harley-riding set.
