Hey oldblues,
Welcome aboard and to the great prospecting hobby...
I have been at it for over 40 years.. consider myself a professional miner... but can tell you for sure.. the first several years, as I look back, I am so glad I didn't quit my day job....
As some have stated here... visit some clubs until you find one you are comfortable being around the members.. find one or two who you "click" with easily and in whom they have some experience...
Read... read.. and then apply..apply.. apply.. just get out as often as possible and pan, sluice, metal detect..or what have you... just remember, it is unlikely you will find much gold laying on top of any stream bed... you will normally need to dig down deep...or maybe to bedrock to locate any gold...but what gold is on top will be a reasonably good indicator what lies unseen deeper...as gold gets bigger as one go deeper into the soil..or stream gravels... Where there is a sand/gravel bar, it is there because of a significant change in the bedrock formation.. when this occurs, usually gold will be found in places like this, IF there is any gold at all in the stream...
Practice, practice practice...Oh..and then more practice, practice practice....
Please always post your questions here, no matter how simple your question may sound to you.. others here will offer you advice and answers... every one here was a beginner at one time in their lives...
Good luck to you... it is a long and slow learning curve..for sure..but a very fun one and if you can endure the curve... it may be rewarding too...
