I'm on Trans Alt's email list and I'm friends with them on Facebook.
I can't remember which way I got the announcement. At the event
I spoke with a TA staff/volunteer, he told me the limiting factor was
the number and the amount of donations from sponsors. After this
years success they're hoping more sponsors will jump on board for
next year, so they can register more riders.
