IMHO:
The positives- You can get a LOT of runs in if you want, a great opportunity to do test and tune if the weather cooperates (no hurricane

) We have made as many as 18 runs EACH at previous events.
Running in the dark is a BLAST!
The late announcement of the event will probably reduce the number of participants = more runs.
The move of the event from CCRs home area of Charlotte to WS may also reduce participation.
For those who haven't done one before, you really owe it to yourself to try it once.
The negatives- JL lot is relatively small and limited in course arrangement due to curbing and islands.
The event tends to be busiest during daylite hours with as few a one run/hr possible. You must sign up for a 2hr work shift per 12 hrs of participation, those savy to the procedures get there very early on Sat to sign up for the first shift on Sat, last shift on Sun when the lines are longest. If you are stuck with work assignments after dark, you'll lose the chance to do the most runs during the best time to run.
Don't leave all your counted runs for the very end of the event or you may not get them in and you'll be very tired and not sharp.
Don't plan on getting much sleep if you want to make very many runs. If you leave the event site for very long you'll miss most of your run time. Bring an alarm clock and nap in the car for 1/2 hr periods.
#1 negative = Hurricane Francis...
