other course addition ideas?

[tbird2000]

Hullo all,

I couldn't find a better place to place this thread, so i suppose I'll put it here. I'm making a course for an SCX10 in my basement out of plastic water bottles (like the Dasani ones) and soda cans, glueing them to cardboard. My question is: what else should i add? it needs to be light enough to carry, removable and somewhat easy to store in a space about the size of a queen size bed around 7 and a half feet tall. I will also be making a bridge out of electrical tape (so it isn't too easy but not too hard for a newbie like me). Sorry for so many constraints, but being thirteen also gives me some budget problems, so anything that cant be found at a Walmart, Home Depot, in a normal household or in a blacksmithing, beekeeping, hoarding lineman's workshop will need to be expensive. I am adept with power tools, so woodwork is not an issue. Any suggestions are greatly appreciated! Again, sorry for the length, but just trying to be thorough of what I do and do not have. Spell Check is one thing I don't.
