In Los Angeles we used to have Road Runner "Extreme", but it was renamed to Turbo last year.
I find AT&T's names funnier. They keep adding new tiers but they sort of painted themselves into a corner when they named their fastest speed "Max". You can't get maxer than max, so now we have "Pro", "Elite", "Max" and "Max 18" and possibly "Max 24". -- AT&T U-Hearse Your funeral. Delivered.
