Thanks dprovan, that's good advice for a newbie. I've let it go, and yes, I'm happy that they found my cache challenging and the stuff inside, worth their time.
Yes, we've been checking on our cache daily. Its a short walk from home. Yesterday, I replaced the pencil.
I am always disappointed to see used junk in a cache, whether the cache is mine or not. But that's going to happen, so I've accepted that!
Thanks all!
