Upper TSOB is a direct connector from Crossover and the Hub Hill area to the top of the Screen Door obstacle, trading views for challenge as it climbs over a run of steep hills. The surface is rough and ledgy, with chunky limestone steps up to two feet tall that demand careful throttle, smart tire placement, and a willingness to hear your skid plates work. It can be driven either way, but northbound is kinder, as most of the biggest drops become controlled descents instead of climbs. This trail may be on the lower end of the difficult scale, but it should only be attempted by modified rigs. Larger tires, stout skid plates, and low gearing pay dividends, and undercarriage scraping is all but guaranteed. Expect a slow, technical crawl that links key parts of the hardcore area of the park.
