Don,
You should mention that the strangest part of the ride was not the "isolated" showers that soaked our a$$. How about the guy trying to thumb a ride by walking down the middle of I-44? I thought he was just going to jump on your bike with you. Glad I had the solo seat on mine. 
hehehe, I was doing my best not to incriminate other
dufii great riding buddies who got caught out in the rain Saturday

. But, yes, that was a Kodak moment.
There we were buzzing down the Interstate at 70-75 in decent traffic. The Road Glide was in front with Travis and his wife on thier bikes and an Oregonian we'd met when pulled off to get out of the rain who happened to be heading our way. That same pull off also saw is visited by two other riders so a half dozen Harley riders all shared conversation and a dry awning for a 45 minutes or an hour. But I digress...
We're buzzing down the highway and I see traffic starting to back up slightly and catch a view of a guy standing on the side of the road. From a distance the first assumption is he's flagging traffic to slow down for an accident ahead.
The Oregonian (whose name I don't think we ever knew) does a zoomie right by me as he doesn't get slowed quite as quickly but, hey, as he went by in the right half of the lane we were close enough to check each others buttons. Special moments like that are always worthwhile.
Turns out the backup wasn't the accident (there was no accident) it was just the guy. He was standing on the shoulder and randomly walking back and forth out in traffic and reaching out to touch cars. He wasn't going to hurt a car of course but I was concerned about our train of bikes.
First one by could treat him like a dog rushing up and buzz by in a lane change. But he might have had a clue by the time the bright yellow Sportster in the rear went by. Fortunately he didn't try to get intimate with a bike and all was fine.
The guy was definitely altered. Slow Motion Charlie all relaxed and buzzed. Bet 103's bike it was heroin or some other strong opiate that had him enjoying the highway so contentedly. All the bikes cleared safely though. So it was all good (for us).
