A crossover jump would work, if you had enough run up, and you oversized the jump so clearing it was a breeze.
Thanks for clarifying the $5 discount thing. If it's only once in a while, I can see the benefit. It still won't replace the work that needs to go in prior to the day, but it will help to prepare the track on the day.
I too would still like to have an open meeting regarding track layout PRIOR to the working bee. We really need to have exactly what we're going to do set in stone so there's no confusion on the day. Hiring the equipment cost money that we can't waste discussing where things should go. And we really need to have only ONE person on the day talking to the bobcat guy.
