We have tons of caches, and I mean tons, in cemeteries here in Texas. There are always explicit rules about only going on this property-type during certain times of the day. This same reviewer also, just recently, published a series of caches in downtown Austin where the some of the caches take you into museums and you have to ask 'someone' to give you a folder. These are free museums, but the second one we went to knew 'something' about it and then went and got someone else. These museums have very strict hours and not everyone is in on the game. The thing is, the cache description tells you that some of the caches on this series can only be gotten at certain times of day, but you don't know which ones until you've spent all morning solving that puzzle only to go to the location and find it's closed. That's it for that day...and that was it for me for that series.
Anyway,I think if you can get explicit detail about gate opening times and put that on the page you should be able to publish those caches. There do seem to be different rules for different caches.
