He has now authored or co-authored over 20 transport-related books. GEOFF PRICE was born on Merseyside, with his life-long interest in trams beginning at 9 months of age (Llandudno). A published author, his varied working life has included advertising (agency and newspapers), property valuation and road passenger transport. He is a former parish councillor and primary school governor.
