The middle of the sportsman class & down have trouble consentrating & running smooth after 17-18 min & alot of contact starts happening just like the 3-5 pileups in the first 1/2 lap till everybody gets spread out.How many times have you been first or second into the first turn & then last out Jeff? I know its happened to me too many times then in the second turn someone comes in too hot & t-bones you again.Thats just the way sportsman class is.
