For a long time we used a photo and then manually entered the code to discover TBs. Nowadays we use an app. That works well, but also has a disadvantage. Quick scan and then you forget to post the log. So now we have to think very hard about where we have seen these TB codes. Well, including at an Event - Cito - or simply in the logbook of a cache, it may also have been on a woodie. Who will know after that time? Despite that, nice that we could discover you!
