For the most part, the day kick off the usual way: tech inspection, rider's meeting, etc. Though they have 4 groups, they rarely run them and don't have that many E4 riders -so- they merge E3/E4 often and only run 3 groups. Since you'll be with E3/E4 riders, we just remind our A riders to give the other riders a little more leeway.
Their registration system is electronic like ours and our systems share registration information. Once you're signed up, they can see it on their mobile devices at check-in. Camping, electric is all-in as well.
