Homemade courses/obstacles?

[Cosmo-Graphics]

I'm looking for ideas of homemade crawling courses. I have a big back yard, but it's flat, so I'm wanting to build myself a crawling course. I am going to get some large rocks and such, but I'm also looking for ideas made out of wood or other non-rock (portable) materials. Any suggestions would be appreciated. Pics/videos would be even more appreciated!

I'm planning on building my own backyard course too this Spring. Found lots of cool pics here:

There have been several topics about this, all with good information. Search and it'll bring up plenty of reading!

When I search "homemade" I get all the chassis threads...
