I doubt I could do a Southeast Wisconsin tour on Sunday the 7th. I’ll be in Chicago for that weekend, but will be reliant on Amtrak and public transportation from start to finish. If the tour winds up closer to Racine and Milwaukee during the late afternoon or early evening, I may be able to join up (I’ll probably have my car parked at the Intramodal).
 
I’m quite sure I can do something December 12. March is iffy, as my spring break happens during the final week, but early/mid March tends to be okay.
