St. Francis Trail?

[Waterfreak66]

Just drove down Hwy. 42 this morning and saw an entrance to a trail called the St. Francis Trail.  The trail marker showed ohv use allowed.  Can anyone tell me if I can park at that trail entrance off of 42 (NW of the River Forest Campground entrance) and give me some information about atv riding on that trail?  I live like 5 minutes away and it would be great to hit a good trail that close.
