As I mentioned earlier, the RNC Welcoming Committee has planned to blockade the Republican National Convention, and here's their strategy as to why.

The geography of the 2008 RNC lends itself quite readily to a blockading strategy--unlike conventions of past years, this one is being held in a city without the capacity to sustain it alone. St. Paul is not big enough. Thus, convention-related events are happening all over the Twin Cities metro area, bringing Minneapolis into the fold. And between Minneapolis and St. Paul, there are still not enough hotel rooms to house the thousands of conventioneers who'll be descending on our cities for four days. So, delegates, media, staff and extras will be housed throughout St. Paul, Minneapolis and the surrounding suburbs, requiring that they all be transported to and from their hotels en masse (mostly on several hundred city buses contracted specifically for that purpose). Thanks to the mighty Mississippi, they'll mostly have to be funneled across a small number of bridges, and thanks to the car culture we live in, they'll only have a limited number of entrances to downtown St. Paul from which to choose. Few conventions have presented such clear transportation vulnerabilities, and we would be foolish to pass up the opportunities those vulnerabilities present. The 2008 RNC is begging to be blockaded.

Tis true, St. Paul is small compared to New York.
