Speaking to my barber yesterday he told me that there is a Putting Green in Howard Park in Letchworth Garden City! It's not a million miles away from Luton, and we've played a course there on the Crazy World of Minigolf Tour before - back in September 2007 at the Par 3 Golf Centre, where there used to be a Putting Course.
According to the Friends of Howard Park & Gardens, the plans for the 18-hole Putting Green were approved in 1943!
While we haven't yet found/or played this 'new' Putting Course in Letchworth, we have driven around the UK's first roundabout in the Garden City.
I'll be heading over to Letchworth in the future to get some snaps and hopefully have a round as part of the Crazy World of Minigolf Tour!
