Hook up with someone that is already into spider rigging and is catching fish. If you can't find someone that will let you tag along, hire a guide for a day and
worry him to death with questions. Find a lake that has decent crappie in it and is a lake you enjoy fishing. Learn that lake until you know where not to fish.
It is a slow process, don't quit. Every year you will know more about what fish want and depending on the time of the year where they are likely to be found.
