What I ve got is a tiny through route map of the city that appears in the back pages of a road atlas covering the whole country it just labels it Dr Norman Bourlong On line there s one here not very good and a pictorial one here Both seem to indicate the name changes to 5 de febrero when it hits the south rim city centre The second one labels it C Norman E Borlaug which indicates that it s a calle street not an avenida The first map spells it Borlaung too must be very common for it be spelled wrong by the locals
