Fishing is like building a fire. Sometimes it is a little harder than it looks. The more experience you have, the better luck you will have. Part of experience is learning the "fishy-looking" spots.
If you have never done much fishing I would suggest picking up a very basic book like "Fishing for Dummies". That is not intended as an insult. I have thumbed through one and it looks like it covers the basics for a beginer.
I do not know where you are, but check the website for your state Department of Natural Resources or Fish and Game Division or Wildlife Division (name will vary by state) Many state, national and local parks will have places you can fish. You will need a licence. You should be able to find some of this info at your State DNR website.
Depends on where you are, but some state parks put on various types of educational programs. I know some states do fishing clinics. Search for your state and fishing clinics.
You do not need to spend a great deal on fishing equipment. You can get everything you need at WalMart or such places. A few assorted hooks, some assorted small lead sinkers, a few bobbers, an inexpensive rod and reel combo and a can of worms and you are in bussiness.
Warning - you might enjoy it !
