Once I went for a cache about half a mile from where I was parked and when I got to the cache I realised I did not have my pen. So I had to re-hide the cache run for half a mile down a bumpy track and run back to sign to the log.
I've seen a lot of trackables that family's or children have which they put in and out of caches but I think it's not as fun as sending a trackable around the world and jumping up to my computer to see if it's gone anywhere.
