I'm the one involved in the US-Dutch geocache exchange with BadAndy. Below I've posted a couple of pics of my cache (The Dutch Yellowstone Cache) and some of its contents which BadAndy will hide close to Yellowstone Park.
I think the exchange idea is great! I hope more geocachers will get involved in exchanging geocaches. As far as I know, BadAndy's cache will be the first exchange cache in the Netherlands (if in the mean time someone doesn't beat us to it). It would be fun if in the future I could go and hunt for exchange caches placed in the Netherlands by others, caches from all parts of the world. Being the first exchange cache and all, I'm expecting BadAndy's cache going to be hugely popular among the Dutch geocaching community.
I also think that BadAndy's postcard idea is really great. I will add a stack of pre-addressed/stamped Dutch cards in his cache also, for Dutch geocachers to send their personalized notes to BadAndy.
I'm also thinking, wouldn't your own exchange cache be a great goal for one of your own travel bugs! Wouldn't that be something if it would reach the cache someday!
Like BadAndy says, we will attempt to keep the caches stocked with trade items. This will keep the caches interesting and the exchange will be kept really alive that way. It's also a nice way for both persons involved in the exchange to stay in contact.
I'm really looking forward to receiving the Yogi's winter retreat cache and to our future trade item exchanges. And I'm looking forward to having my own cache hidden close to Yellowstone Park, an area I've always been fascinated by.
