Multiple Trackables in a Cache in Trackables Posted April 8, 2013 One cacher thought it was bad form to take a TB and not leave one. I thought it was okay to take a TB and move it to another cache without leaving one - I didn't have one to leave. Please comment on the proper procedure - are you suppose to exchange or can you just take one to move it on? There is nothing wrong with taking TBs and not leaving others in return. TBs are not exchange items, they are meant to travel. And if you see a cache where the cache owner stipulates that you have to leave a TB to take a TB, you should take all the TBs and move them along. TBs belong to the person who released them, not the owners of the caches they rest in.
