VAL AIR DURANGO COLORADO FIELD CHECK FLIGHT

I go down to Val Air to fly my Asw 20 and I was kinda surprised that they tell me I'm going to have to take a field check flight first.
I had actually interviewed with owners Bev and LaVerne St. Clair about being a commercial ride pilot for them, as I has giving rides and towing at the time in Telluride.
They said everyone had to have a field check and I think, OK, probably not a bad idea as Val Air looked a little challenging, Barb wire fences to take your head off, tall trees on the approach to miss, hangers to hit, the Animas river right there that you could really blow it and go into, etc etc and it's in a fairly narrow valley.
So I rig and go up to see Bev in the kiosk to get a field check.
LaVerne is going to be my instructor. We get in the Blanik L 23 and I ask him what are we going to do? Oh normal stuff he says, stalls, slow flight coordination exercises. As the slack comes out he says " Your Airplane"
Off we go and everything looks pretty good when at about 6-700 AGL, LaVerne yells " THERES THE TRAIN! LET GO! I'll TAKE IT"
The Durango -Silverton tourist steam train was coming by and LaVerne pushes over into a zero G dive and gets in 2 passes next to the train, below powerline height, at redline, which I was keeping a eye on.
He does a low level 180 and lines up to land in a full performance slip. He asks me if I'd like to land it. I decline and he lands short so we don't have to push back too far.
"How did I do I ask?" Your OK he says.
I doubt that flight lasted 2.5 minutes.
Later when I'm paying my bill I ask Bev if I have to pay for that checkout.
She asks if I learned anything?
I said, Sure did! Don't hit the train!
She waived the checkout fee, sweet gal she is.
