I know of a real interesting Homestead Multiple foundations, The largest is made of stones, there is an old boiler still there, it's made from rivots, According to the Map on the website it belonged to John Schultz.. It is at the NW corner of 147th and Central, you can get there from Bachelors grove but it is a good hike down the trails best bet is to park in the apartments at 147th and Central walk across the street and it's just inside the woods... I hid a Geocache there So if you do that it is easier to find, Here is a link for the Geocache, Some kids built some type of forts there as well..
