You're right, blue is mysterious, seems endless, and gives you the possibility to imagine all sorts of things. You love to fly! Good for you. I have a kind of altitude sickness and am not at all happy in an airplane, I only flew twice a long time ago, in the last century... Now it's a handicap not to be able to fly. I missed the destinations I was interested in when I was younger and now I only travel by car, nearby.
