You can petition to MSHSAA for a waiver in the travel restrictions and it is a once a year waiver that is extremely hard to get. Petition in writing well in advance and you must convince MSHSAA that it is almost a once-in-a-lifetime opportunity for it to be granted. Oak Park got the waiver to attend the Super 8 duals and I think Blue Spring was granted a waiver to attend the Clash, both of which are prestigious, invitation only events which helped their case. As far as I know, those are the only waivers tht have been granted in the last 5 years. When Oak Park got their waiver, I know it was a VERY big deal and many people couldn't believe that it happened. I think the organizers from the Super 8 duals were involved in the petition discussions with MSHSAA in order to get the waiver.
