At the request of Detroit Diver & Harley Diver, we're planning double dips on the Spiegel Grove all day on Fri 2/18. We plan to remain onsite above the wreck for two hours in the morning, and again for two hours in the afternoon. We'll return to the dock mid day to "refuel". Mixed gas is BYOB. Experienced wreck divers feel free to PM me for details.
