Searching a cache starting with an H

We brought a travel bug from Denmark that wants to stay in caches beginning with the letter H. We couldn't find an appropriate cache in Denmark, so now back in the Netherlands and after our 300 milestone reach it was time to find a cache for it.
We decided for the cache (GCZEDB - Het Loon), a nice multi cache, we took or bikes to get to the start.

It was a nice walk and when we arrived at the stash location and started searching for the box, we found a black bucket buried in the ground, we immediately thought that the cache was ripped and went home to inform the cache owners of this misfortune.

Back home I read the last logs and figured out that this black bucket had nothing to do with the cache ......
We went back early in the evening and could log at 18:20.

And because we were on the road we decided to go for another one (GCKZ0D - 8 zaligheden: Duizel), a picture cache that we could solve by driving around and go for a short walk we could find the stash at 19:40.
