I have 3 dates in mind. All are Saturdays. April 13, 20, 27th. I don't think these will interfere with any holidays. Weather dependent (has to be at least 60F+ and no rain).
If you like to sleep in, this isn't for you. Meet at the meet spot in Huntley (90/20) ~7:30am, on the road by 7:45. Should be back around 5-6pm.
Here's the link from last fall.
