After a call to the shipping company, a visit to the campground office, and a second and third examination of everything in Rover, we found the passport in one of the outside storage boxes and have no idea how it got there. But it was a huge relief and will keep us from having to contact a US embassy somewhere. The only benefit to all of this is that we have packed and repacked everything several times and now know just exactly where everything is. And we still have some empty cupboards.
We then drove south to the area around Ypres, the site of one of World War I's bloodiest battles. We caught up with the "Flanders Fields" tour signs and followed them around the narrow streets in the center of town...and out again. The tour took us to several British cemeteries 
and to the museum in Zonnebeke. It was all very stark, very sobering, very factual. The museum and each of the cemeteries had registers in which visitors were invited to record their thoughts.
We have now stayed in three different campgrounds. All have been very clean, quiet, and well kept and we have felt very safe. The first two had many permanent trailers and we saw very few people. They apparently come out only for weekends. Because we are now in the “low” season we aren’t even bothering to make reservations--we just show up, and there have been lots of open spaces for us. We are now in a campground just outside of Amsterdam where there are many tents and motorhomes here for short stays.
In spite of the fact that we brought with us at least half a dozen different electrical plug adaptors, we had yet to show up with the right thing. At the first campground we were able to borrow the right cable and then we were able to find an RV shop in the neighborhood and bought a long extension cord with the proper connector, but then at the second campground even that wouldn’t work. They loaned us a proper connector and then today we were able to purchase that same item to use at the present campground. (See "Things They Don't Tell You" #3-4.)
When we left the campground in Belgium this morning we needed to find an ATM. We were turning around for the second time in a large parking lot when a young man pulled up beside us and asked “Are you really from Minnesota? Can I help you?” We told him we wanted to find an ATM and he told us to follow him. We drove just a couple hundred yards around a couple of corners and parked in an open square. He told us to walk around the church where we would find a bank and he would meet us there. We did and he did; he then invited us up for coffee in his apartment just upstairs of the bank. It was great to have a good cup of coffee and also to have someone else to talk to. He had sent some time in various US cities and was eager to hear how we had shipped Rover. He graciously answered all our questions about road signs and then gave us his phone number and email address in case we had more questions in the future. His hospitality was so generous and genuine. It really made for a special beginning to our day.
