Since I started caching I have always wondered: Is it bad caching etiquette to find a cache, see an interesting TB and decide to take it to continue it on its way without leaving something in the cache in return? I almost never trade for items in caches anymore, just sign the log. I enjoy the challenge of finding the caches and being outdoors... So, please advise me, is it alright to grab a TB without leaving a trade item? Thanks!
