Checked for NYC, but says it has only data for US. Where actually is data available?
I ran "New York, NY" with a 5 miles search and got some results -- what did you query specifically?
Says there is only data for the US when I tried to search in the UK
Ah yeah, that's still the default error message. If you're searching in the UK you'll probably want to search a bit closer to where you expect trails to be, eg. Crowden, Glossop, UK
Let me know where you searched and found nothing and I'll look into it!
