I have taken a tour on the Red Bus in Oxford but not in London. I must say it is a nice concept but why take a bus when you can walk? I have walked a lot around Oxford and a little around London. And if I was ever to do it again, I would like to walk even more.
I have slogged and slogged in January, and went to Gwalior for work. Let us see how I fare in February, I have no complaints with slogging but I wish I will be able to pull of a weekend trip this month.
