It seems that no Norwegian home is complete without a trampoline in the yard. We played a version of "Slug Bug" to entertain us during our long drives where we would slug each other every time we saw one. After awhile, our arms were sore.
The most bizarre trampoline-in-yard experience happened as we walked through a residential area in Bygdoy, which is a part of Oslo. As we walked to the Kon Tiki Museum from the Viking Museum, we passed a yard where three boys, probably eight or nine years old, were jumping on a tramp. About half an hour later, as we walked by on the return trip, two of the three boys were stark naked, still jumping on the tramp. And it's not like this was in some backyard. It was in a side yard right next to the sidewalk. Those nutty Scandinavians!
