The corn is 8 feet high!

I did end up having one issue today -- after I stopped to take the above photo, I went to start the bike back up, and all I got was the 'click' of the solenoid. It didn't trigger the starter. So I turned the ignition switch off and on, made sure the bike was in neutral, and it did the same thing. Eventually it did connect with the starter and I was on my way. About 20 miles later I stopped for gas. The same thing happened, only this time it didn't ever engage the starter. I ended up having to bump start it, and headed straight home. I checked all the connections when I got home, and everything seems to be in order. I still have the 'click' of the solenoid and nothing more. The lights, horn etc work, but not the starter. As an aside, I did put the battery on a trickle charge yesterday, as I hadn't ridden the bike in a few weeks, but I don't think that necessarily is connected to the 'clicking' of the solenoid. The bike started normally this morning before I left for my ride, and it started again normally when I filled up at the gas station around the corner from my house.
So is the starter dead? Is the solenoid dead? How do you tell which might be the possible culprit (if it is either one)? If the solenoid is making the 'clicking' sound, does that mean it's good? I looked up how to 'jump' the solenoid with a screwdriver, but I'm not really sure how to do it with confidence.
Any thoughts???
