pointer80, when it concerns private property, yes, you can detect till your hearts content, as that is under the control of the property owner, and they can do whatever the heck they want with their own land.
But as it concerns public property "in Kentucky", you do not say which level of land you are referring to. Because public land can be divided into federal, state, county, and city. All levels of which will have various land in each state. Right? So your question is too broad.
And let's assume, for sake of argument, that you meant state level land (as opposed to city level, county level, and federal level). Kentucky is one of the state's that got a simple "no", on the FMDAC's state-by-state list , and had the reputation of getting some purist archies in the university there, to propose even stricter cr*p, and making some very anti-md'ing statements that got picked up by the press, and repeated on many forums as a "sky is falling" lament from md'rs.
But let's assume, for sake of argument, that in fact, state-of-Kentucky state parks really were off-limits (just for sake of discussion here), that STILL would have no bearing on county and city level lands, which have their OWN rules, for their OWN parks and schools. In other words, simply because county and city are within states, does not mean that, therefore, state rules subrograte down to parks and school and beaches and such that are city and county. PARK RULES DIFFER ALL THE TIME from location to location. For example, one park closes at sunset, while another allows over-night camping. One allows dogs off leash, while the other requires leashes. One allows fireworks, while another doesn't, etc... So simply because the state of Kentucky may have gotten this reputation (d/t some links to some archie statements there), ONLY has bearing on state level lands, not other types of land within the state.
And there is another thing to remember: the FMDAC list (which gives a simple "no", in the kentucky column) ONLY applies to state parks. You have to remember, that "park" land is only one form of the entity's land. In other words, there's lots of state land, that isn't necessarily a "park" of theirs. For example: state road right-of-ways (as roads extend out for various distances from the edge of the pavement, for walking strips, utilities, etc...). Those are not "parks", but are still state land. And so on, and so forth, not all state owned land is "parks". And the point of the list (way back when, when it was assembled decades ago) was inquiries sent out to the park's dept there, and didn't necessarily pertain to every other speck of land (be it other types state land, or county or city land within that state).
