Yes - the rule is "not corded when the tech inspector looks at 'em." Seriously, wear bars are usually at 2/32" IIRC, which is our typical minimum. Just keep an eye on 'em between runs to be safe. Worst case you have to stop a few runs early because you see cord patches.

Yes - there is on site registration for any unfilled spots, first come first serve starting at 11am. Although it's way too early to trust any weather forecast. We don't run on the oval in the rain anyway. We would either wait it out, postpone the event, or shorten the course to involve just the flat sections.
