90x60 track layout ideas?

[RC-Monster Mike]

I am finishing up a dirt track in my back yard - hopefully this weekend if the weather permits. The track is set back in the woods, so pretty much surrounded by trees on 3 sides and is about 90ft long by around 60 ft deep. I would love some ideas for a track layout if anyone is up to the challange.
Ideally, it would have a crossover jump somewhere, a small jump series(double, double, double for example) and a table top/corner table top somewhere perhaps. It would be great also if the track was designed in such a way that moving a few pipes could yield a different course or two as well. I should have the track surface done soon and will be on to the layout, which may very well change a few times before I am happy, but hopefully some folks here can submit some ideas that can be implemented!
