I enjoy riding alone most I must admit, 2,3 others max by choice
When I ride with someone for the 1st time, I make sure we agree on a few basic rules with regards to things like space and speed.
Space especially when it come to my immediate left or right. I want no one (barring emergengy) there..... I dont want to take anyone out, nor be taken out by a momentary lapse of concentration that can happen to each of us.
TMAC will see me in a group setting since a looong time, I will make sure I understand the rules it comes with. If you prefer basketball rules over soccer, do not join a soccer match....
