I agree a bit more diversity is needed and it could be done. I went to Hengelo recently (where is that I hear cried aloud). In the Netherlands and it is not the big Hengelo you will find easily on the map but confusingly the little one, in Gelderland but nearby. A nightmare to get to by public transport but I got there. It is organised largely by the local farmers, a once a year event, and is a real road race and they had the lot - 125s, 250s, classics, supersports, Dutch superbikes and the 3 Nations Cup plus, for the first time, the Women's European Cup (big grid for that). No sidecars though, sadly. The local farmers put up stands in amongst their crops and the whole event is fantastic AND VARIED. Well worth a visit and the stands are free, I think, but it shows what a bit of local enthusiasm can do. One interesting problem for the racers amongst you. It had rained a lot for the 2 weeks prior to the event and rained immensly hard from the Friday night through practices on Saturday, until Sunday morning. How do you wheel a race bike 150m through unbelievable mud from a tent to the start line in a fit state to race???? I'll tell you how we did it later.
