I travel a lot on the tubes and buses, why? because I have to, and we have a great transport system here in london. Yeah the system has it's moments,and we do sometimes moan. It can be a bit much with all it's engineering works and midnight closures, which some people can refer to as a "Long Ting"(annoying,frustrating,time consuming,or just plain and boring) but overall it is great. Wait until you go into other countries and see what they have to deal with for public transport.
