I just went online and purchased my 2011 fishing license. Pretty simple. Here's the link to get you started (those of you in California).
Just click on the Online Sales and follow the instructions. took me less than 5 minutes. Only one glitch, they only take Visa and Mastercard. You can print a temporary license and the real one will be mailed to you and you should recieve it in 15 days or less.
If you need one that is other than a yearly resident license, I would suggest you go to one of the License agents (Go to the link at the bottom of the page and fill in your fishing store information to see if they are a licensed agent). Here is the link for you to go there direct.
I entered Fishermans Warehouse in Sacramento and it gave me their information as a licensed agent.
Happy fishing in 2011.
