Have you tried geocaching? If you haven’t Fresno is a great place to start. You don’t have to go far to find a variety of creative ones. This is a cache idea I stole or should I say “borrowed" from one made by Terra Girl in San Dimas. (She in turn was inspired by another cache.) I had to have help, a lot of help to figure out her puzzle so don’t get discouraged
By the way I am shamelessly proud of some of the caches I have made and would encourage you to check them out if you haven’t already. Sadly many have been archived but their pages still have something to offer.

P.S. This cache has been placed with permission by the property owners. You will be seen if they are home. Just wave and smile, you are there for their amusement.
