Infrastructure decay in the US, has left many Trolls living in dangerous conditions, with nowhere to hide from hobbits on a quest. 42% of all bridges are at least 50 years old – which is certainly true of Jeff & Beau - and 46,154 are deemed structurally unsafe to ambush a billy goat.
Traditionally Trolls would sit under a bridge demanding a toll from any who pass, but nowadays most like to bait people on Twitter. Said one Troll: ‘Bridge safety may not be interesting to you but to me its riveting – literally’.
