I've just had my eyes opened I commute round Sheffield and appear to be looked at as one of the few 'loonies' for doing this. I've been away with the family, for the weekend, for a family wedding. My 1st visit to Cambridge. Didn't even get into the centre. Stayed on Newmarket Rd and all the 'functions' happened in Fen Ditton and Quy Theres only 1 phrase - cycling culture shock Parked up to check the map and passed by half a dozen groups on bikes. Now all I've got to do is either move to Cambridge or encourage a 10,000% increase in cycle use round Sheffield!!
