Just got back from the rally. It rained off and on so didn't take the camera.
There were quite a few K's at the rally of various types; One nice K75, a couple of K100's and quite a few K1100's and K1200's. Seemed like there were more GS's than any other particular model though. I was on the only K1 that I saw. I didn't see any vintage bikes; did see a very nice /5 and quite a few late 70's through 90's airheads.
The rally goers were relatively unfazed by the rain. Several tour groups went out throughout the day. Nice rally all-in-all.
