My bike helmet is off to you, sisters, what great accomplishments! In my opinion, there can never be too many tiaras.
Responding to the rainwear question--here in the land of rain--I have had success with the REI jacket; I forget the name, it is the yellow and grey one. The "tail" in the back actually is attached by velcro to the inside when not in use. It does a good job redirecting the water. There are also waterproof (well, supposedly) shoe covers. I haven't tried them, but hear they help, although water can splash up through your shoe clips.
The bicycle is the most civilized conveyance known to man. Other forms of transport grow daily more nightmarish. Only the bicycle remains pure in heart. ~Iris Murdoch, The Red and the Green
