The Cutler Park stage is really great. The bands are drawing huge crowds yet there's still room to move without feeling crowded. It's unreal how dark the park gets on moonless nights - and it doesn't help that everyone is wearing black.
I don't recall the last time downtown streets were closed for a flood of people instead of a flood of river. It's Friday Night Live all weekend long, free music and lots of people strolling. Stores open late and doing good business.
Lots of sightseeing. Every bike is personalized in some way. I haven't seen any other countrys besides Canada represented. I saw a group from Japan five years ago at Rider's Ranch. This year there is no Rider's Ranch at the Expo.
It's amazing how loud a custom chopped bike can be. Fortunately my own neighborhood has been quiet. Even my younger bike-riding neighbors haven't been partying at all hours.
The best bargain around for $2.00 is a 15 ounce bag of Pinas Chris Mix found in a tent at Riverfront Plaza. The second best $2.00 is spent on a snowcone. The snowcone syrup wasn't very sweet, but it was a fundraiser for a good cause, Salvation Army, it was a warm day, and a stranger thanked me for buying it when she saw me with it later. 
There's a Harley-Davidson exhibit at the Waukesha County Museum? I waited until this weekend to see the Lennon exhibit because I also wanted to see the bike exhibit. There were a few photos of bikes and Harley family members, even a bike or two, but the main exhibit was the Lennon display. It's too bad the Lennon exhibit alone wouldn't have been enough to attract viewers. It's also too bad that almost no mention was made of a fundraiser for the Les Paul exhibit. But at least something was done and I hope it helps.
Parking hasn't been a nighmare. I parked by the State Bank, the Waukesha Antique Mall and Corrina Blvd., none of which is very far from the action.
And they're saying we need rain. Just not this weekend, please!
