short answer: yes.
long answer: you can find the clues to many multi caches/virtuals if the items are waymarked.
we know about them, but they like to ignore us--just last week at a cache event, as soon as the W word was out of my mouth the guy said 'thats just a bunch of McDs crap'......
oh well, guess hell never find the many things i have posted (so what, at least 4900 of mine are NOT McDs).....
