I'm going to Bermuda and have heard from friends who've been that there is a company that offers undersea walks - like diving, but old-fashioned diving where you wear a helmet connected to a boat. I would love to do that! If anyone has been on one of these walks/dives and could provide me with some information and details, ie where in Bermuda it's located, what the cost is, what the company is called, and so on, please do!
