aarn.com

they do a good job of covering the northeast and larger national races. always have writeups about larger non wing sprint races such as speedweek, ect. the owners sons are racers.....one in a pavement mod and the other in urc/410 winged sprints.
any local larger race you will find the owner in the pits talking to the teams.
its a bit pricy on the newstand but well worth the subscription price.
