I'll keep my fingers crossed then. Scottish is, unfortunately, a bit too far for a day trip for me, though
This is an excellent idea - I have had the good fortune to visit West Drayton and Swanwick, and the opportunity to chat to controllers has been fantastic. It certainly helps appreciate the hard work that goes on at the other end of the RT; the more PPLs who can visit ATC and understand how it works, the better for everyone - and hopefully fewer airspace busts.
