YES! This is the way to do it. When the pilot gets to "Dolly" on the
checklist, a quick look to the side confirms it is off. It helps if
your dolly is a unique color not to be confused with another.

I'm new to gliding so excuse my ignorance, but shouldnt the D(olly) check
be done before you get into the plane or is there no standard on the ABCD
checks?
Rather than checking that the Dolly (or someone elses that looks like
yours) is on the grass to the side it would make more sense that you
confirm, regardless of whos Dolly it is... it isnt attached to the back of
your plane?
