I believe I have found a great spot for a geocache. It is on the property of a favorite classy restaurant with grounds that are very "park like" with walking paths, a footbridge, a pond and fountain, etc. It's a beautiful place and a great restaurant. The closest existing cache is a mile away. I'm wondering how to get in touch with the owners do how to ask permission, should I send a letter explaining what I want to do and why and asking him to contact me? Is there a basic letter already made up for this, like the note to muggles that is placed in caches? Suggestions?
