Anthem won by default of being the only one to show
Anyone care to try this again, now that I bought all the equipment to run it:
4 cones to lay out start and finish lines
4 stop-watches to time 4 riders simultaneously
2 radios to communicate between start and finish lines
1 notebook to log everybody's times
Thursday afternoon / evenings would work best for me, though I could probably do it on a Saturday afternoon / evening as well.
I can't do anything Saturday mornings because I don't usually get to bed Friday night until 5AM or 6AM Saturday morning.
