Hey guys, I'm going to Atlanta tomorrow morning to the SX race. This is the first SX race for me and my 7 y/o son. I read that the gates open at 12:30pm and the event does'nt start until 7pm. Does it pay to get to the event super early? Is there plenty to keep us entertained until race time? Is practice open to the public? I can't seem to find out any scoop on the daily "goings on". I'm driving my motorhome with lots of MX videos just in-case the day is slow. ANY HELP?
