I was recently looking up some old drag-racing info about a dragstrip in 
Northern California,
the "Vina Raceway" near Chico, CA. I just obtained an old 1968 issue of "Super 
drag racing magazine, which had a feature article about this Vina Raceway 
which was in operation from 1963 to 1968. I was not able to attend any races 
there, but I remembered
seeing the advertisement posters posted on phone poles all over downtown, for 
an upcoming Sunday afternoon
drag race at Vina Raceway in either 1965 or 1966, while I was still in high 
school in Southern Oregon. 
Some of my friends went down to the race, and told me that there was a very 
good turnout from our town, which was probably a four or five hour drive away. 
The big turnout was probably due to all the advance advertising that had been 
done in various Southern Oregon/Northern California towns.

Many years later (1980's), I learned to fly in northern California. While 
looking at the 
San Francisco area sectional map for visual navigation, I noticed near Chico 
that there was 
a place called "Vina Mat." Seeing that on the map reminded me about the drag 
races back in 
the 60's at Vina Raceway, and I did some research on the 'net to see if I could 
find any 
info about it. Since that area in northern California is a major agricultural 
area, I guessed
that a "mat" must be something to do with grain that was being loaded and 
transported to other areas.

I had no idea what a "mat" was, until I did some more searching. I found out 
that a mat ("landing
mat") is a large grouping of metal (usually steel) plates tied together, in a 
that can be installed as a big, solid surface for aircraft landing and takeoff. 
I also found 
that many of these "landing mats" were installed around the country, as well as 
especially in the World War II era, as auxiliary airfields and airfields that 
needed to
be built on short notice. Large areas of land could be covered by these steel 
mats by an
installation crew in a short time. Some of the completed mats were square, some 
and some were in yet other configurations. Some mats were simply hooked 
together, some were
bolted together, and some were even welded together.

The Vina Mat was a typical, large (3100 feet rectangular) landing mat near 
Chico, California 
(north of Sacramento). The National Archives depicted the field as "Chico 
Auxiliary Army 
Airfield #3" - there were five satellite airfields used by Chico Army Airfield, 
which was 11 miles to
the southeast. It was built by the military during WW II, and was used to train 
fighter and bomber
pilots. It was a rectangular, paved landing mat, and the rectangular shape of 
the mats 
permitted aircraft to land land in any direction, eliminating the possibility 
of a crosswind.

Some airport guides still list this as a private airport, and it's now called 
"Deer Creek Ranch Airport (CA60), Vina, CA".

The reason I bring all of this up about the steel landing mat system, is that 
it appears that there may still be
many of them around the country. I'd be curious to know if any hams ever bought 
one of these properties where
the metal mats are still in place, and if anyone ever attempted to use it as a 
counterpoise for an HF vertical array. It seems like a nearly solid, 3000' X 
3000' steel plate mesh all tied together would be
a great "radial" system for big vertical arrays. 

Did anyone ever try operating HF mobile, with the car parked on top of one of 
these mats? It just sounded like something that would be fun to try. You'd have 
a difficult (and expensive!) project laying down a radial field like one of 
these old landing mat systems! 

Listed below are some of the articles about Vina and other nearby landing mat 
airfields, landing mat
system development and history, and a landing mat manufacturer/dealer. Some of 
them have excellent
photos of "now and then" views of a few of the airfields.
