So. I did it. I hung the sign I made for ALAN, it was everything I ever thought it would be. Super scary.
It felt naughty, excitably so, to go out in the dark with the sign in my bag, with the tape and a small pair of scissors, just incase.
I scoped the area 3 times using 3 different vehicles and at different times of the day/night before I got the nerve to tape the sign to the bridge. It was windy and raining, I had to battle the elements, onlookers and the very real presence of law enforcement driving around, searching for people up to no good.
I left the sign in place for a couple of nights, long enough for people to see it, short enough for me to retrieve it.
Note to self : Next time you hang a sign made out of a sheet on a bridge outside in real life, use rope. Not tape.
