These are all good reports, thanks guys!
Since the clinic is nearby (and I can fit it into my schedule), I will definitely sign up to audit 
I actually had PLANNED to go audit (the organizer was expecting me) the last time he was here about 5 months ago, and on my way there my tire warning light went on
- I had a nail in my tire - so I wound up spending half the day at the local mechanic getting it changed out. sigh So much for the clinic!
(Strangely, I was on my way to audit another clinic with a BNR eventer last month, and I got ANOTHER tire warning light: this time I had a slice in my tread, AND a screw! Again had to replace the tire, same place - they are local, at least, and we buy tires from them so if they have to repair or replace a tire, it costs less.)
The joys of living in construction central NoVA.
Or maybe I should just stop planning to audit clinics, LOL!
