Dan Levy, who worked for years in Silicon Valley as a marketing exec, doesn't ski and used to get incredibly bored on family ski vacations. So he started Captain Avalanche, which specializes in high-tech sleds. The sleds can go up to 50 mph and make sharper turns than normal sleds. The sleds come with a foot brake, too. Ultimately, the price should come down to around $149 to $199, he said.
