I'm pretty sure I know how to solve the Olives are good cache. I found a similar cache here in So-Cal. As for Jackie & Bob caches, they are tricky. I met Bob when he lived out here, and his puzzle caches can get down right evil at times. He is very cool, so e-mail him if you get stuck. Tell him ShowStop said hi!
ShowStop.... me EVIL? I think I know of the puzzle you speak of. Now that I'm retired I have even more time to think about puzzles. Say hi to my So. Cal. geofriends. Kestrel Trap... the owner of that one is a good friend of mine. We like puzzles.
