The Putah Creek Riparian Reserve is a great place to take a walk. It is a little under a half mile from parking to the cache. If you bring kids with you, hang back a little after you spot it and let them make the find.
Remember: Found it logs that don't have a corresponding sign-in on the log are subject to deletion. We don't go out of our way to check for sign-ins but you should not trust that will happen. If you cannot sign the log because it is too wet then a photo will suffice. If you merely forgot a pen or pencil do not log a find, go obtain one, then return to sign and log.
