Track Layouts?

I have the opportunity to build a fairly large track (if you consider ~100ft x ~50ft large) at my Stepdad's MX/Camping area :) . I was just thinking of a good layout (~1/8 buggy sized) that would fit the space. I'd like to see other people's thought up layouts to give me some ideas, here's my layout, don't worry about all the sharp edges, those would be rounded, of course. :L:
