There are many non-US based SLers coming to the Convention. Many aren't doing it as a "one day thing", but as part of a vacation, business trip, or trip involving other projects. Besides that... ITS TWO DAYS! Saturday, and Sunday.

That being said, I'm a dual citizen - half US, half UK, and while a lot of the crap that's been going on the past few years pisses me off, I'm still proud of both of my countries.
Here's a lovely letter from an unknown source that pretty much sums it up:
"dear red states,
we're ticked off at the way you've treated california, and we've decided we're leaving. we intend to form our own country and we're taking the other blue states with us.
in case you aren't aware, that includes hawaii, oregon, washington, minnesota, wisconsin, michigan, illinois and all the northeast. we believe this split will be beneficial to the nation, and especially to the people of the new country of NEW CALIFORNIA.
to sum up briefly: you get texas, oklahoma and all the slave states. we get stem cell research and the best beaches. we get elliot spitzer. you get ken lay.
we get the statue of liberty. you get OpryLand. we get intel and microsoft. you get worldcom. we get harvard. you get ole' miss.
we get 85 percent of america's venture capital and entrepreneurs. you get alabama. we get two-thirds of the tax revenue, you get to make the red states pay their fair share.
since our aggregate divorce rate is 22 percent lower than the christian coalition's, we get a bunch of happy families. you get a bunch of single moms.
please be aware that nuevo california will be prochoice and antiwar and that we're going to want all our citizens back from iraq at once. if you need people to fight, ask your evangelicals, they have kids they're apparently are willing to send to their deaths for no purpose and they don't care if you don't show pictures of their children's caskets coming home. we do wish you success in iraq and hope that the wmd's turn up, but we're not willing to spend our resources in bush's quagmire.
with the blue states in hand we will have firm control of 80% of the country's fresh water, more than 90% of the pineapples and lettuce, 92%of the nation's fresh fruit, 95% of america's quality wines (you can serve french wines at state dinners) 90% of all cheese, 90% of the high tech industry, most of the US low-sulfur coal, all living redwoods, sequoias and condors, all the ivy league and seven sister schools, plus harvard, yale, stanford and MIT.
with the red states on the other hand, you will have 88% of all obese americans (and their projected health costs) 92% of all US mosquitos, nearly 100% of the tornadoes, 90% of the hurricanes, 99% of all southern baptists, virtually 100% of all TV evangelists, rush limbaugh, bob jones university, clemson and the university of georgia.
additionally, 38% of those in the red states believe that jonah was actually swallowed by a whale, 62% believe life is sacred unless we're discussing the death penalty or gun laws, 44% say that evolution is only a theory, 53% that saddam was involved in 9/11 and 61% of you crazy bastards believe you are the people with higher morals than we lefties.
by the way we're taking the good pot too.
you can have that dirt weed that they grow in mexico.
sincerely,
author unknown in new california"
