All this chat about the track is great
My comments are coming as a DMCC club member, I'm not on the committee nor do I have any say greater than any other club member.
Obviously no decisions are going to be made on Oople

but its good to see what club members might want.
The DMCC committee can decide if they want a track changing team(TCT), if yes then this is what I propose:
1. The TCT get suggestions from racers who should have a design worked out. No point in saying 'I want a better jump'

you need to have something on paper (ideally a picture of a jump from another track etc.)
2. The TCT team put the suggestion(s) to the racers. This could be done during a normal club race day asking for a show of hands on who would like the change(s).
3. The TCT would then and only then propose these changes to the DMCC committee who will then make the final decision. The DMCC can look into the costing of the jumps and the scheduling of the build etc.
4. The TCT team then organise the building of the jumps depending on the decision of the committee.
I think the above allows for everybody in the club to have their say and for alterations to take place but also restricts any individual from altering the track to suit themselves.
