I lived on the Isle of Man (search for Isle of Man TT races!) for 7 years or so and have always regretted not getting a bike! It would be so much handier (trafficwise) now that I've moved to London.
I'm limited to trips on the back of my brothers bike in Ireland (Honda Shadow).
Also, married now, so I don't think a bike is allowed, maybe not until I'm all grown up, maybe when I'm 40, mid life crisis etc
I'll settle for my nice comfy BMW 5 Series in the mean time!
