Building a Car Wars Arena

[jbjsignup]

I am looking to put together a list of things to consider when drafting your own arena for Car wars. Any suggestions welcome whether...
- Obvious - "It should have walls"
- A small detail - "Give buildings DPs"
- An element to consider - pillars, pits, ramps, water, etc.
- An idea - "Booby Traps"
- A crazy idea - "Wheelbarrow Wars!"
- Something that worked for you - "a figure 8 track"
- Something that didn't work - "Wheelbarrow Wars"
- location - middle of the desert, parking garage
- back history - how it came to be
- a track idea - L-train in abandoned city

I hope to put all the ideas and some of my own into an article.

Thanks.
