If anyone is looking for a cheap/affordable gravel navigational TSD rally that starts/finishes in the vicinity of Calgary then look no futher

The event needs entries and checkpoint volunteers!
The scenery tends to look something like this (albiet a bit darker):
requirements are a registered and insured road worthy vehicle equipped with a first aid kit, fire extinguisher and a warning triangle.
there is also a novice school a few days before the event.
