There's some good information in this document. For example, on page 2, it states that UTSA has sold more than 13,000 season tickets for the 2012 season.

"FILLING SEATS: Last year, UTSA sold 11,600 season tickets en route
to establishing an NCAA startup program record for average home
attendance (35,521). Playing their first season as a reclassifying FCS
independent, the Roadrunners drew nearly 10,000 more fans per home
game than FCS leader Appalachian State (26,211). That figure would
have led the WAC — Hawai’i was the top draw at 31,785 — and ranked
second in the program’s future home, Conference USA (East Carolina,
50,012). As of Sept. 3, more than 13,000 season tickets have been sold
for the 2012 campaign."
