It means that they make that claim. Reality may differ, at least in my local area. Anyone can make a plain curbside historic marker into a virtual cache, but then hype it as a nice urban hike by recommending that you park a mile away. I think I will hide a lamp post micro at Wal-Mart but give the parking coords at Target in the next suburb, call it "Off Target," and rate it a 3.5 for terrain due to the length of the hike.
I'm curious why you're posting your question here rather than in the Terracaching forum.
Well because I already looked over their site and wanted to get the opinions of others who may have done some caching from that site. Besides their forum is pretty limited until you get "sponsered". As of now I am not sponsered. Additionally I wanted to get a different take from the geocache community.
