What's the geo-caching etiquette for re-establishing a cache at a site that had a cache at one time, but has been archived for some time? I noticed while surfing the geo-caching site the other day that there was a cache relatively close to me that has been archived since May 2005 and it appears as though the owner hasn't done much with it since then . . . for that matter it appears as though the owner isn't doing much geo-caching at all . . . although he appears to have visited geocaching.com as recently as last week.
