I recently logged a virtual cache on Nevis whilst vacationing. I thought this was safe.
I also placed a micro there but have not logged it yet as I read the maintenance aspect and was undecided.
I would be interested to know of the 142 countries with caches, how many are active because of vacation cachers or because of indigenous cachers? I personally would like to look for a cache in a country I was passing through in order to have another country on my found list (I do like stats ), and if it's not there I can log it as not found.
Maybe when you entered a vacation cache into the system there could be a field to flag vacation cache so people would not be surprised if it wasn't there.
I can understand the idea of maintenance to prevent your cache contents being thrown around and causing a problem, but some of the foreign caches will be visited so rarely that cache abuse shouldn't be a problem. Even if there are maintenance visits, anything could happen to the cache in between visits?
