I could just kick myself! While caching this weekend on a quickie road trip, I picked up a TB at a cache in Lompoc and dropped him off on the way back home in Ventura. I realized when I got back home and tried to log my "retrieval" and replacement....I DIDN'T write down its tracking number!!! I did email the owner yesterday to see if he could send me the required info, but I have not heard from him as of yet. Any other solutions to this kind of problem???? HELP!
