Iowa Speedway C-E-O Doug Fritz say the first Nationwide race in 2011 drew more than 37,800 fans and another big crowd will watch this weekend. Fritz says tickets for this weekend are still available.  Log on to www.iowaspeedway.com for tickets, or call 1-866-787-8946. The website also lists the start times and schedule of events.
