Lost my hat black outback type with red bandana around it and flower on the front

[Sunshine2day]

I lost my most favorite hat, I have a very small head so it is hard for me to find hats that fit. This is a outback/cowboy type made of almost like a cardboard type material. I had a red bandana wrapped around it and a little flower on the front. I think I lost it around 5 and E there was a big party and I got caught in the middle of it trying to get to my camp. At one point an art car was trying to squeeze through and although I was standing still trying to get out of the way and a Ranger was telling them to stop, it dragged my bike and me opening up my hand, I am pretty sure this is when I lost it. I was so shaken by the ordeal I didn't realize my hat was gone. Please if you found this hat if you can return it.
Thank you!
