We have never got in to the whole pathtag thing but have a few we have earnt through GCA finds and a few we've collected from other geocachers.
It wasn't until the recent series where you could claim finds on ones starting with certain letters that I looked at the website for them. I logged the last 2 we got as I could remember where and when I got them but as for the rest!! Who knows where and when.
Have included the required photo of our measly collection.
Thanks.
