At one point I actually did an inventory and loaded it into a spreadsheet on Google Docs. I was around 700 total and it was a couple hundred rows with all the different makes and models. I did really good for a while keeping it up to date, and I even wrote an android app that I was going to switch over to. Then summer bbq season came and I started to lose track of it as I'd bring a bunch out and forget what me and others smoked. I came to the conclusion that I really don't effing care what I have. I know I have too many, that I'll continue to aquire them, and it's kind of fun forgetting what is in the fridge.
