DO NOT- I repeat, DO NOT- miss that ride.
You're young yet, you could 
quit your job and it'd still be worth it.
Feels good in that seat, doesn't it? 

And I like his placard: pretty much the only rule worth remembering! 

Took only one ride in a Stearman so far (with Ed DelRosso, brother of the Dom I mentioned)... wish I'd asked for stick time, but I was shy about that at the time... flies like it's on rails; everything a heavy, powerful bipe should be. 
Don't make the same mistake I did: ask if you can have the stick for a minute or two. And request he demonstrate at least one steep chandelle, if not a stall.
Let me know when you're going- maybe I'll fly or drive out and take pictures... and maybe bum a ride... 

He gives rides for hire in that plane, yes?
