Just curious if this was frowned upon. Many areas I travel to I have "cached out". I have to walk because my company wont get a rental. So my cache coverage area is limited and sometimes already covered. If there is a trackable in a cache that I've already found can I move it on to another destination? I like seeing new trackables and helping them get to their goals. Or, if a trackable that I placed in a cache several months ago is still in that cache, can I pick it up and keep it moving?
