Break out the tents!
...and man the pumps! Batten down the hatches, maties!
Seriously, it's already getting congested- I had about 4 near wrecks this morning- strangers who didn't know where the "H" they were going suddenly darting across 3 or 4 lanes of traffic without signals.
I am going to try to fetch some better maps to illustrate how the mainland & barrier islands are laid out, how the causeways look, and why these annoying protesters have no earthly idea of what problems they face merely trying to get around, let alone get into secure areas.
OK, I can't link to a better map, but click here to see more details of the mainland, islands, and causeways:

See all that blue-white area with sprigs? That is salt marsh- you can't walk through it without bogging down. It accounts for much of the apparent land mass in the islands and mainland, and this means you just can't set out to go from point A to B without using a road or crossing watery areas. That's one impediment. And then...
St. Simons is separated from the mainland by two Intercoastal waterways- the Frederica and Back Rivers, and they are deep enough for pushboats ( wrongly called tugs ) and cruise ships. Plus there are many smaller rivers, creeks, and bog-holes 'twixt Brunswick and SSI. The Torras Causeway is the only way besides boats or aircraft- and these will be easily controlled.
Once you reach Saint Simons ( SSI ) there's one more causeway- the Sea Island Causeway- to cross before getting anywhere close to the G8 gathering.
There is one other little thing outsiders know nothing about- both Brunswick and SSI are so old that many, many streets change names, veer off in weird directions, and generally don't go where you thing they ought to- it really confuses non-natives. I grew up giving directions to lost & befuddled tourists.
