A dad recreated Disneyland’s famous Matterhorn roller coaster, right in his family’s backyard. The extraordinary homemade amusement park in Napa Valley, California stands 26 feet high. It features waterfalls, hairpin turns and even a fearsome yeti. The stunning remake was created by Sean LaRochelle, a dad and engineer who started construction in the early days of the pandemic. With help from friends, it turned into a massive project that took four months to complete.
