I have no problem with beginners we all were at one time. Riding in a big group being safe and having fun totally relies on the TWO leaders in the group. The front person has the obvious duties. The tail man has even more to do with how things go. He is the one that has to watch for the wrong side of trail riding and at the next stop put the fear in them to never do it again and why. He keeps track of the speed whether too fast or too slow and relays that to the front man, and with that if its a big group then some radio communication is almost a must. yea it cost some money but so does all the other gear you went and bought. When a group is spread out you cant wave a hand for the leader to stop. If everyone is a beginner then it is difficult to learn everything so just drive a safe speed and think of the trails as you would a major 2 lane road driving with your 16 year old with the family car.
yep I agree and I think what happens a lot is a group puts the fastest rider in lead which puts pressure on the slower riders to ride way beyond their experience and make bad decisions - I rarely lead because I can't control my speed, I am better off in the middle or tail man, the best solution is to get a long track and go exploring off trial! make sure Lenny is with you or carry a lot of gas for when you are trying to find your way home!
