Silver Fox, the parks I've hunted here never really gave up much either. While waiting on the weather to warm up earlier this spring, I made a significant discovery in research for my area. In the next county East, called Noble county...was looking at the town of Wilcotville in Google maps. It is just a small town with a population under a thousand, on the Noble/Lagrange county line...might actually be in Lagrange county. The Blacklegs gang according to US Treasure Atlas had a hideout South of town in the swamps near there.
Anyway, found a small park just SW of Wilcotville while looking at the close up maps I printed out. Seemed to be an ordinary park, but tried searching the Internet for Noble county to make sure it wasn't one of those historical preserves. I have a county park near me on the river, but is called a river preserve. All the old cellar holes, canals where a riverboat once operated are all preserved. I didn't find anything to indicate that, so am assuming the park SW of Wilcotville is open to detecting.
My search brought up Noble county info including historical. Here is the local historical account for the Blacklegs gang.
In the early history of Indiana, there was a famous band of horse thieves and counterfeiters who had headquarters in this county. They were called "Blacklegs." this gang was notorious all over the United States, and every township was infested with them, but the safest place was in the northeastern part around Rome City at a spot called "The Tamarack." Here is where they made their bogus money. In 1852, the State Legislature enacted a law authorizing the formation of companies of "Regulators" to put a stop to their operation. Several companies were formed in Noble County who soon overthrew the "Blacklegs."
I wasn't trying to uncover some new info, but seems to be alright...the gang headquarters was between Rome City and Wilcotville. Rome City is South of Wilcotville. Plus look at this...must be from an old newspaper they quoted.
One mile north of Rome City, on the site of the abandoned town of Northport, is a Catholic sanatorium known nationally for its treatments and baths. The scenic resort, Sylvan Lake, was formed in 1837 as a reserve reservoir for the canal to connect Northport with the Wabash and Erie. One of the interesting points is the old dam site on the banks of this old canal, which was never completed. In the town of Avilla is a Convent, established in 1876.
Seems like a good area to consider since towns are tiny...rural setting not many people around to get in your way. I'll bet the Blacklegs gang used the park to relax or hold small talks there...who knows what might be found.
