Grizzly Riders T Shirt Contest

Here's the deal. The 1st member to answer the following question correctly will receive a free GR T Shirt in size Large or XL. No staff are eligible and as with all contests you must be a regular status member (10 posts or more) or a site supporter. Well here is the question. Name all 3 members whose grizzly pictures were used in creating the back design of the GR T shirt. Sounds easy enough doesn't it? It's not who you would think either....well not all 3 any way. Want a hint? There are clues listed in the old design threads when we started work on creating them. Each member can have 2 shots at guessing. After that your done. Post your answers in this thread....Good luck!
