Lost two tickets for the Bakersfield Music Festival in an orange envelope in downtown Bakersfield.

I lost my two tickets for the Bakersfield Music Festival while walking around downtown last night. They were in an orange envelope which also had a receipt from the purchase inside. I remember taking them out to check the date, and I must have dropped them when I put the envelope back in my bag. If anyone finds these, I would be super grateful, as it was a special event for me.
