This one is rated a bit more challenging, because it's 25 minutes or so from I-95, about 4.5 miles down Bailey Mill Road, a dirt road, in an out of the way place that sees very few travelers. You will find (look carefully!) an unmarked, somewhat overgrown car path leading directly to the river; pull off on that and walk down toward the old dock pilings. Just before the river, take a left, and in 25 feet or so, you will see some of the old bricks and pieces of the boiler that fired the old mill. I left a FTF piece (retrieved by PeterC3611 shortly after publication!) and some other SWAG that you might find interesting in this double boxed cache.
