I’m in the Springs as well. We live in a city that is very detectorist unfriendly for sure. They just modified the city ordinance which states that we are allowed to detect on public land (parks, etc.), but we are not allowed to dig or otherwise disturb the soil in any way (basically limits us to surface finds). Further, we aren’t allowed to keep anything that has “value to man” or is over 50 years old- even a clad nickel can be perceived as having value to man. So, in other words, they have pretty much outlawed detecting here without outright outlawing it. I plan to start looking for areas outside of the city limits.
I know there are a couple groups here in town and a few larger clubs in the Denver area.
