When Hades came over earlier in the summer to help me set up for DragonCon, there was one project we left out of the photo galleries. We spent one day performing an inventory on my Super Soaker Collection. It took the entire day, but we displayed everything and did a proper tally of the different models. There are 269 Soakers broken down into 168 unique models at the time of the inventory. You can find the pictures and details at a page we've set up here.
