Argh man !! Sheez ! No body tell my wife !
When we go on a bike trip .. I handle it kind of like when we go camping (with wife, 1 teen 1 preteen girls).
I tell them lay out all they want to bring along.
Then I do the denials.
Does each have to bring a hair dryer, curling iron, straightening iron (why would you need one if your bringing a curling iron ?

), one gallon of shampoo and conditioner each, makeup .. makup .. who the heck wears makeup on a camping trip ???

.. this is just the tip of the iceberg !
... Im sure you see what I mean. ...wouldnt give 'em up for the world though.
