Nice video - really nice. Great experience with the kids. Let me ask you this. Can you read in the V-Birth in conditions like that? That, I find, is the big test as to whether someone will get sea sick.
I have never gotten sea sick myself. However, I have noticed some changes in the last couple of years. A few times if I go on the tilt-a-whirl too many times in a row, I will start to feel really sick and weird. That has never happened before. On the boat, there have been a couple of times that long, slow waves seem to start making me feel strange. But not the rough stuff - yet. We just took the boat down to Crowleys to put her to bed for the winter in like 6-8 footers and it was easy as pie. Others came in with full foulies on acting like it was rough. Our boat seem to take it pretty well.
