Thank you! The darkness is starting to get on my nerves! We don't get a lot of big waves here, I wish we did! The immediate waters around here are pretty sheltered, but as you move west along the coast of the island there are places with EPIC waves. Tofino is one such place, famous for storms and surfing. What we do get around that island are strong rip tides. I'm glad you enjoyed the "higher math" :)
