I keep mine listed in my signature, along with date of purchase. I had a fever for purchasing for a while, and then my shooting was reduced by weather and the police knocking on my door. For about 2 years I was shooting in the yard as a break daily from my computer grind (my day job was computer oriented, and I do work from home, also in computers), and then I was relegated to the garage... I had fantasies of moving to a place where I could shoot outside again... and then lost my day job which might have afforded the change. I have nicer guns now, I shoot less, and work even harder to make up for what I lost. When it all evens out, I've got great shooters to look forward to, and some projects as well when I find some leisure.
Cheap chinese guns sparked my interest, and some awesome tuning by Gene refined my pleasures. I'll find a way this spring!
