Cars driven by BK Racing teammates Landon Cassill and Travis Kvapil will feature photos of the girls at the Pennsylvania 400 at Pocono Raceway on Sunday. The decals also will include a phone number for the National Missing Children hotline.

Ten-year-old Lyric Cook and Elizabeth Collins, whose 9th birthday was Tuesday, disappeared July 13 while riding their bikes in Evansdale.

Cassill is from Cedar Rapids, Iowa,

''Being from Iowa, and having some other folks in the sport from Iowa, we're all pulling together to raise as much attention as possible to help locate the two missing girls,'' Cassill said. ''I really want to do as much as possible and this is one step. I can't thank the team enough for doing this.''

Kvapil hopes the effort will put a national spotlight on the investigation.

''As a parent, I want to do anything I can to help the families locate their children,'' Kvapil said. ''I'm pleased that we have the special decals on our cars this weekend and I hope that this will aid in the search.''
