In search of my bag

Hi. While I was volunteering I set down my bag for a short amount of time and it was taken. It was left on a rock in the side of the trail by the humane society. If you’ve found it or seen it I would really appreciate you letting me know. It has cost me a lot to replace everything and pay to reprint things. The keychain from Niagara Falls was also special to me. If you found it and want a reward I can trade you something like one of my house plants. Thank you for your time.
