Then do what I used to do: Borrow a neighbor's internet without their knowledge! 
or if your uber 1337, put a satallite dish on your house  and attatch a cantenna, then get an ENCRYPTED wi-fi signal, crack it, print off a sheet on THEIR printer saying "I hacked you wi-fi and there ain't nothing you can do to stop it" then sign it with some l33t name, THEN start playing. 
ooh 
take pictures too. 
Seriously, just pick up a neighbors wireless network, like redchlorine said.
