Tony,
Unfortunately, you've hit the mark! We're (SCCA SFR SOLO II) still going to
try, through the $5 site-fee-per-entrant fund, to develop a "proprietatry"
site but, the reality of this goal is cooperation. Unless we are able to
find a "partner" to share their acerage, long-term, with our "paving-fund"
the chances of getting a good bay area (or even close-to-bay-area) site are
limited. We have to continue to try and find a connection (and add to the
site fund in the meantime) as the only logical path to a really good chance
of getting a good surface to run on.
There are few lots we've used that make most folks "happy".All have
compromising characteristics over time and with the various weather
variations throughout the year.that render them "good" only occasionally.
But then, the alternative is boredom --- and not throughing money into the
black hole of autocrossing.
I want to keep throughing!
Don
