years ago i just got into a taxi with my bike! driver didn't batt an eyelid! that was between stations in london and i've even seen people with bikes on the tube! i nip up to london every now and again and find if you take your time looking for the signs it's not to hard but it took me a while to feel comfortable using the tube etc, was paranoid i was getting myself lost! but then i am a complete idiot with maps! :?
