Basically when you're there and you pay for the flag....... just keep it for next time. No sense of throwing five bucks for a flag every time you go.......... got a CB??? no? get one! it's a must. Also, there should be a list of things that you need on the trail,,,,, I've seen it somewhere......... (like tow rope, first aid kit, drinking water, fire extinguisher, etc).
Join NOIEC, we are planning a run in Wisconsin too!!! there is a tread here too, look for it, join in and pick the date!
Later,, this time for sure.
