Treasure hunting for my future bottle tree

I was helping my friends work on the gazebo again today out in Granger. I arrived a little early and walked through the creek looking for treasure. I found 8 bottle of different shapes and sizes. Most of them are clear with a few brown ones mixed in. I plan on looking again next time to see what else I can find. From what I hear,  there used to be an old stagecoach stop down the creek and the patrons used to toss their beer bottles into the creek.
