Would you go?

I understand what you're talking about Andrew.. .I'm just pointing out
the problems if you don't have such a device...

I would have done the same as you. I would have made it a point to
monitor CHT's and EGT's on taxi and runup (I know what normal is for my
plane, and fuel cintaminated with jet-A will not yield normal operating
temperatures) and I would hav done a full-powe runup on the threshold
for a few seconds, again monitoring CHT and EGT. My logic here is that
I would catch water contamination by drainign a sample, but hydrocarbon
contamination is trickier.

Having said that - I would take off knowing that if something did
happen, and they had indeed parked the truck there to keep me from
taking off, the accident would be called pilot error and the monday
morning quarterbacks would blame me for launching when something was
obviously not right.
