I live in middle of Europe in a smaller city. Most of survey sites I came across can work for big cities in US. If you live in Big Apple, Washington DC or other big city give it a try.
Earning around 10 bucks in an hour for answering few surveys sounds good. Bummer is when you take a test to be accepted and you are not. After 20+ minutes of work.
If the surveys are available and you can make it every day for a month it can add 300$ to your income.
Give it a try and remember, not to join any paid site. There are free sites with nice surveys.
