Ooh, I've not seen Nerdy Day Trips before; I'll have to get in touch and see if they have an API (probably a better chance than the others I've been working on)

Ooh, I've not seen Nerdy Day Trips before; I'll have to get in touch and see if they have an API (probably a better chance than the others I've been working on). Location data like that would be very useful (and I'd be very grateful for it), as it would help resolve a number of issues with geocoding some of these places. There's probably a castle or two that are registered as being in a terraced street, for example :D
