To get around my sister's part of Belgium, we used bikes. She and Sven kindly borrowed (and bought!) enough bikes that we could all ride around.
One day we visited an amazing bike shop. I test-drove this incredible cruiser. It was like driving a vintage Cadillac, only with a bit of the 21st century thrown into the mix. (Several gears - but hidden in the rear hub, for example.) The bike was made by an American company, but I forgot which. The shop was filled with "upright" bicycles - but not many mountain bikes. That style is very popular in Belgium, as there aren't many hills to contend with - at least compared to Colorado!
Alas, it did not fit into my budget or our luggage.
