The owners of the nearby house are aware of the cache, but are enjoying the cache and are watching over it. The hotel should be safe :)
Park at these coordinates in the parking lot N42.42.368 / W86.10.091. There is a trail that starts right near this corner of the parking lot.
There is no need to go off the trails until you are almost at the cache.
This is a good place to drop off bugs that may need to head towards I-94 West, I-65 South, or I-80 East or West.
For those heading to Chicago Which Way to Lake-18 'ChooChoo Charlie's-TB Depot' is a good stop for bugs just off exit 1.
