Enjoying a nice sunny day, just like Frank and I were! Now, those horns???? I've never seen a plane pull up behind another one and toot "beep beep, outta my way!". (I know it's a stall warning horn!).

Actually, the horn-looking devices are the venturis used to create a vacuum for the instrument vacuum system (which drives the attitude, heading, and turn&bank indicator gyros). Newer Skyhawks use an engine-driven vacuum pump to perform the same function. The Skyawk's stall warning horn is inside the airplane, and is connected to a stall sensor located on the left wing.
