Halton Moor
There's a guy flies an Allouette (or llama or similar - I'm a plank driver, so please excuse my ignorance) from his house in Halton Moor. There's a helipad in his back garden. Someone on here might know who I'm talking about. You're talking 5-10 mins in a taxi to the City Centre from there.
Shame you can't use the massive car park thing that used to be a market at Cross Green.
