Its unlikely they'll be released on a national holiday although I hope they do, anyways I'm betting on tomorrow because they're usually released before the projected dates. Happy Independence Day to my fellow Americans!
They don't send anything in the mail . You can get all approriate info on your account and on the lsac web site. About 2 weeks before he test you'll get an admission ticket with your photo and the address of the the testing center you chose.
When LSAC knows what the release date is going to be, why don't they send out an e-mail with the updated date? Does that make too much sense for their liking? The amount of lost productivity due to people not knowing when grey day will be is mind-boggling.
