I dare say you all know about Michael Bojkowski's Linefeed, one of the best design blogs out there (and the one I've probably been reading the longest, in various incarnations). If you don't, pop over there and have a peruse – it's well worth a few units your precious webtime.
One of the highlights is his ongoing typosurvey of the City of London, where he casts his eye on those little designy gems scattered about the sprawl. I'm particularly looking forward to his forthcoming photographic adventure around Golden Lane Estate and the Barbican (one of my favourite places on earth). Now that the sun has come out, I'll have to pop out onto the streets of York and do my own typosurvey at some point.
