check out Home | showdownsrt4 for some pictures and info from the last show. If another gets planned for this year (i'm pretty confident there will be) information will be posted there as well as here and all over the facebook groups.
TONS of srt-4 related facebook groups! i cant link you to them because i access this forum from my work computer which is government owned, so i'm not getting on facebook here to get links, sorry. You can search facebook and find plenty of groups though.
