Hi Brendan Elaine and Colin here. Don't know if you remember from Dumfries Rally we talked about my Kiwi 5 yr old grandson's love of planes and air traffic control? He's visiting with us in Bishopbriggs until 15th Sept. Would a visit to your place of work be a possibility at all? Not a problem if not convenient etc. Just thought I'd ask anyway. Cheers email@example.com if you prefer.
