I used this OLN-budget glitched canvas of Sandbox. Bungie.net : Halo 3 File Details If you don't delete any items that are already on the map, you can get a huge amount of items on the map... which will allow you to create a full skate park. Download that map and save it. Use it to create all your maps on Sandbox and you'll get many more items on the map.
Hay thinks dude send me a freind invite on xbox live.My tag is [You by cat] and mabey we can make a map together.
great idea.i just saw a skate park on foundry but your is very cool too. maybe you could add some more think you got so much object and so much space on sandbox.but it looks very clean and very nice.
