One of my family members is selling their house soon and I want to know if I can post a virtual cache near their house so people come and see what a beauty it is as long as it is .10 miles away from other caches. I know this is not the traditional way of doing virtuals but I wanted to see how other cachers felt about this or if it is against the rules. Thanks.

I found a benchmark while geocaching nearby but I can not seem to be able to log it. Am I missing something? It is not listed at being nearby the cache I found. Please help advise.

I like it. I also like the idea of making them different and unique.
