Its behind Glasgow airport.

Go along the M8, coming from the clyde tunnel way, pass the airport cut off, pass the next one directly after the airport, and take the following exit, come to the roundabout, go round, pass the greenock cut off and take the following before going back onto the M8 heading back the way you came. follow the airport perimeter fence till it stops on the right and go down the small farm looking road "walkinshaw" road it's called and ava is half way up on your left, hope that makes sense

You still got the S1?
