I'm sure there will be the a statement somewhat like "the economy is causing us to reduce our expenses, and participating at the Tomahawk Fall Ride is a casualty...yada yada yada". But is the real reason tied to the ongoing contract talks? I'd bet so. H-D is still providing demo rides & more at other 2010 events.
It may not affect this years's participation as many attendees will not be aware of this change until arriving, but it will negatively effect attendance in the following years if this is the new status quo. That could be a big drag on the already soft northwoods economy.
Or perhaps H-D management didn't get the memo stating the bridge replacement does NOT start until after the 2010 Fall Ride?

For those whom dislike the Fall Ride, sadly you wish maybe coming true.
