I was supposed to go to London yesterday (and do the Baker Street Hidden London tour i had to cancel due to illness last year) but guess what... i am ill again so didn't go (and there was a rail strike too anyway). I think this tour is cursed for me so i probably won't try for a third time (lucky).
Instead i walked the canals in central Birmingham, walking the Birmingham & Fazeley Canal from Farmer's Bridge Junction through to the Worcester & Birmingham Canal as far as Bath Row. Its an ill wind, the canal walk was finr though i was looking forward to the Baker Street tour but that is life.
