dear Tomas, this answered the question I asked you about paddling when the wind and tide against you, thanks. "had to paddle really hard to not be blown backwards. great exercise and love feeling that power." POWERFULLY, MERRILY PADDLE YOUR BOAT GENTLY DOWN THE STREAM, LIFE IS BUT A DREAM (otherwise, it could be a nightmare, saying you were trying to get home against it, and it is getting dark, knowing your wife is worried?) All depends on our attitude right.
