Major League baseballer Mark McGwire was said to spend his off-seasons in Adelaide as he had friends there and could walk the streets completely unnoticed. Bruce Springsteen found something similar last time he was in Australia.
The point is, though, McGwire didn't visit sport stores and browse the baseball bats, and Springsteen steered clear of guitar shops. But I guess Stephen King just couldn't help himself when he was sprung surreptitiously signing books - his own presumably - in an Alice Springs bookstore. A few years back King drove a motobike around the backblocks of Queensland unannounced. Seems he's on a similar excursion this time. Just do the Aussie thing - leave the guy alone.
