I would suggest groups of 5 trucks or so, to keep the groups moving along. I'm very "go with the flow", so just throwing that out there.
Maybe some of the guys who went last year and who know the trails somewhat could be team leads: BTUMan (probably knows the trails better than anyone), WillyBeamin, CodyAustin5, and Kreiten, Atwalz, Steenh, Slee, or myself as other possible "team leads" if they are interested. This might help organize everyone into groups of 4-5 and choose trails for each day.
The up side would be more efficient trail-running and ease of keeping track of everyone in your group/team. The down side would be that people would not get to socialize as much while out on the trail, with people in other groups/teams.
Then again, we should still all meet up for dinner and drinks later on, regardless of what we decide. The 4-5 truck team idea would help for coordination of group text messages; they could be relayed among the "team lead" and each lead could disseminate information to his/her group.
Or lets just jam 20 LC's on a trail and see what happens! I'm good either way!
