Posted here for you to copy - maybe you have DIY time before your trip.
Just an update - that new helmet I purchased turned out to be to small - I don't know why I didn't notice in the store but I realized it sat WAY to high on my head. The upshot of it was I actually had 2 different people shout encouragement at me while 1. riding up a hill and 2. just riding down the street (You can Do IT!, and some thumbs up) as I think the disparity between the size of the helmet and the actual size of my head (whilst being an all white helmet - a la hockey helmet) made me look mentally challenged.
In any case I bought a proper road bike helmet that fit, which didn't have a visor, so ended up ordering the Blackburn Road mirror. It attaches (or is meant to attach) to the break hoods, in my case I have it attached to part of the drops. It works quite well for my purposes, shakes a lot - but I think I prefer it to the helmet method. Bonus is it can easily detach from one side and be moved to the other side of the drops for Europe.
