After that, follow Nick Papageorgio everywhere he goes!
Chris,
Hello and welcome to Tnet...
Please pay little attention to halfdime...It seems he was dropped on his head shortly after birth...

...but he still is a pretty cool guy...
Any way St. Louis holds a lot of history...in the mid 1800's it was the 4th largest city in America. I am not sure what part of the city you are in but as long as you do a little homework and research you are bound to find some good stuff.
Always ask permission on private land...the public parks and schools seem to be good...contact the MDC on the state park end...they have a list of do's and don'ts plus you will need a state park permit...they are free via email MDC...
Good luck and we are looking forward to seeing your finds,
Nick
