A penny's worth of thoughts

ok. so i was working my way through finding sources. i had decided that i wanted to do something with public space, so i started with that as a search topic, and quickly realized that i needed to be much more specific than that. so, i tried looking up some stuff on sauer and the biologicaly distint borders, but the info out there was a little shoddy, so i changed my focus again. i then considered doing research on the internet as a public space, the limits it has received and the ways that it is being used, but once again came up a little dry for hard articles on it. then, i thought about maybe doing advertisement as public space, and how advertisement is used through clothing and billboards. I haven't gotten around to doing a whole lot of research on that one yet, though i kind of like it as an idea. so, if any of you all have any ideas on what you think would be a good topic, or have any resources relating to any of these topics that i could borrow, that would be wonderful. thank you all for your input and i will see you in class.
