You could also head up into Wisconsin and take your time heading towards the Milwaukee area. Catch the Lake Express, http://www.lake-express.com/htmdocs/...ess/index.html
, and end up in Michigan. You could check out the Harley plant. That place is huge. The ferry crossing is 2.5 hours on the express and there is a slower ferry that takes about 4 hrs to cross but I'm not sure where you can pick that one up at or where it lets you off. Here are the prices for the express. Not bad if you do a one way into Michigan and ride home around the lake.

Another really nice ride for the weekend would be to head up to Norway Michigan. It's about 2 hrs north of Green bay. The sign says welcome to the South West UP. I was just up there a week ago. They have some really nice roads. Just watch out for the deer and the wild turkey. I almost hit some of those. From the Chicago area by car it's about 5.5 hrs to get up there so a sport bike could make it in alot less time. Not sure about a Hardley Davidson tho.
I'm sure whatever you do you'll have a good time. Let us know what you decide and have a good weekend when you're gone.
