Looking for Trolls

I took a different route on the walk into work this morning, and it lead me under this road bridge over the canal. There was something wholly intimidating by the passage under that bridge; whether it was the low straight ceiling, relentless in it's oppressiveness, or the thunder of cars and lorries above me, i'm not sure.

Like my fellow commuters, I hunched down and picked up the pace just to get out from under it; eyes darting from shadow to shadow, looking for trolls..

I think I'll stick to my normal route in future.
