I just put two studies up on the website. The first is the original
that was in the Feb Endurance News. I is the same as you read in EN but
the graphics are a little better at showing trends.
The second looks at the distribution of the regions of the riders in
rides in the 9 AERC regions. It is quite interesting and it does show
some differences. I'm not going to tell the ending - you'll have to
read it for yourself.
