I'm in MN too
about 10 mi SSW of MOA or 20 mi SSE of downtown Minneapolis. But I don't drive so anyone who wanted to detect with me would have to come here (AV nr BV border). Yes, I'm in a metro area of 3.2 million with nobody to detect with. My dad used to detect with me about 1976-1985 & we detected about half the towns within a 200-250 mi radius.
Now that driving is more expensive & silver coins fewer, most detect near home or at the nearest old place. If people live in N, W, or E metro, they detect nearby or go into Minneapolis or St. Paul. And people from S of cities not likely to want to come N where there's more detecting competition.
There's only 1 pre-1963 park within 5 mi of me & oldest school 1965. I don't mind just finding clad, as long as I don't look at others' old coins on forums. I mostly like detecting public property as I don't like to ask to dig up a stranger's yard. I've got research on hundreds of thousands of places public & private near & far but know I'll never get to 99.999% of them.
Lost Treasure site has long detecting buddies list, but they don't require annual updates, so the person may be dead, have quit the hobby, or moved away, so that's my excuse for not trying to contact anyone on there lately.
Maybe I will get the motivation to take the bus to some different parks here in new suburbia- at least I might get more clad. HH, George (MN)
