Can someone point me to more info regarding what the expectations are of green, blue and black trails?
It's basically a guideline. This year for CANVAZ we are going to have several different runs depending upon interest. As a general guide, a Green trail is anything stock and no real off road experience necessary. A Blue trail will have some obstacles that a driver will have to negotiate and it may be best to have some form of tire other than street and maybe some other minor modifications like skid plates or some rock sliders. Off roading experience is more helpful. A Black trail is for the modified crowd with off road tires, armor and generally a rear locker with good to very good off roading and recovery skills. Blue and Green trails generally involve little risk of damage to a vehicle. A Black trail has a good possibility of damage or breakage.
Jayrat and I have not yet compiled a list of trails and types yet but it's in the works. With each trail the expectations will be clearly set out with what to expect. The trail guides and cat herders will be experienced and will have vehicles that are probably a little more capable than the trail requirements as a whole. As the lists come out of the trails each leader will set their idea of what to expect but it is up to you to be prepared and bring extras such as plenty of water, some food and warm clothes and/or a blanket in case of a nasty break. Nobody will be left behind but you surely don't want to be that guy that shows up without water and the like thinking the trail leader is going to supply everything. There is nothing wrong with attempting a higher class of trail to polish up your skills. When the runs get posted then would be the time to ask the trail leader any questions you may have if you are thinking about it.
This is shaping up to be a really good event this year with lots of participation. You will find a good attitude and a willingness to help out with tasks go a long way. The trail leaders/cat herders put a lot of time and energy into making it a great time for everyone on the run and they get a lot of satisfaction when they see people smiling or talking about how much fun they had. Hope this helped to clear any questions up about the general rating scheme.
