New scrapper in MN

Hi I'm a new scraper and I have a few questions

1. what are your best bang for the buck newb locations... I'm thinking about walking down the Rail road tracks and looking for things dumped other than that I don't really know

2. what are the things you normally pick up, TV's...appliances...siding...computers?

3.what are some realistic prices of striped down TVs and appliances, are some things not worth grabbing if you are new

also, I have a full time job so I'm just looking for some weekend extra time extra cash, so I'm not really in to driving around on garbage day or starting a recycle business or anything. I'm just in it for the treasure hunting feel I get when scrapping. so far I have just grabbed things my work is throwing away and I have made a few hundred.
