Julie,
I found the AA web site to be a great source of information about what to carry (emergency equipment), and one of the few places that had the differences between requirements for cars and for bikes (e.g. Headlight deflectors, hi viz vests etc).
Also used the "Best Biking Roads" web site, for some recommended rides in the area we went to.
There's nothing like personal experience though, e.g. noisy pipes etc. (Bikes, not the people you're with!).
A good idea I think.
