You are going to face tougher and tought times unless you settle down and get certified somewhere. CA is just starting out and the process seems relitively simple right now...Next year you'll be required to have a ticket before you can work but right now if you have applied to take the test you can get work if it's available.
One thing that you need to start doing is contacting those people you worked for and with and get notarized documentation on co letterhead indicating the kinds of work you have done. Keep those records and if any state licensing agency requests a copy you will have to send them a notarized copy of the original.
Pretty soon they are gonna shut the travelers out and then when they need them they'll be up a creek. Trying to maintain licenses for more than 2 or 3 states at a time is to expensive and time consuming.
RickMand's "California Cretification question" might be a worth while read.

while you're on the subject how many different license classifications for electricians and electrical contractors are there in Montana?
