Cerberus’ voice carries a mile out

Cerberus glanced down the road. “How far are we from the Mount?”
“Little over a mile. Too far to walk before dark,” said Lady Bee. “A bunch of blowouts and a nice, high-pitched brake squeal on a quiet evening. Every ex for six or seven blocks is going to be headed this way.”
“Any guess how many that is?”
She shrugged and held her walkie up in the air. “Five, maybe six hundred. We’re still too far to get a walkie signal.”
“We’re being jammed,” boomed the titan. “There’s something broadcasting wide-spectrum white noise nearby.”
