Going to SEMA:
You need to be either media / press, or an exhibitor.
Go to the SEMA web site
2009 SEMA Show | Home
and see if you can qualify as media.
If not, go to their list of exhibitors, and try to go with one of them. It costs $25 (I think) for extra passes.
Some of the exhibitors will have Italian branches, and you might be able to "work" for one of them - take pictures for them or something.
