Helmets are fine when the sun shines, but if you’re
in a monsoon I find the cheesy plastic shower caps from the “No
Tell Motel” will keep your head dry. They are far from a fashion
statement, but they really work.
I've tried various shoe covers, but the lightest
and most impervious to water that I have found are the plastic bags
that shelters your morning newspaper. They’re cheap– always
important for the discriminating bike tourist– and if you have
really big feet use the Sunday Edition.
