I live in the 'abnormal' north
. I have seen a few of these around - am always astounded by the sheer size of the wheels. They seem to appeal to younger mums mostly.
It's a bit of a backwater here without any major pram/pushchair stockists, I have been known to stalk people show extreme interest when I see something out of the ordinary. Nearly passed out when I saw my first BJCM in Tesco last year and bombarded the poor lady with questions :)
