I love your kelp photo's Rdbkorn.
I just saw a documentary with 'fields' of kelp in China (you get that when China hosts olympics), they even make rooftops from it.
I love the mountain from a plane photo too, by Outofcontxt.
About making photo's of public buildings : it's sad they want (to teach) you to be intimidated. I hope you will never be.
About what I shot this weekend : I was in a abandoned factory. I too love abandoned buildings, but my country has a lot of people and not much space, so abandoned buildings will not stand for a long time. But, I was in one, and... after 12 shots with my Holga I noticed it was on B all the time

I had other camera's too with me, which I used also, and maybe something will get out of the Holga, I don't know yet ( I don't develop my own film)
