I wonder if they will shut down the servers at night, and will it be open or will you have to get some type of one off WEP key to access.
If not you could sit in your Car at night, or the Day for that matter depending on the location of the McDonalds and download to your hearts content, depending on the speed this may even be faster than on my 1mb at home, could even be an SDSL
Edit: and you guys are starting to take the McMick with wall the Mc'ing
