Seriously, I keep a checklist of stuff for every trip I make out.
Obviously, I don't bring everything on the aforementioned list, but I find a list very helpful so that I don't overlook anything in a mad rush to get out.
If you're driving a few hours to fish, it's better to have something with you and not need it than need it and not have it.
I have a separate list for boat trips. I hate it when I have a boat trip and want to surf fish afterwards.
The list is much shorter if you're flyfishing.
Unlike all the other crap I listed, you really can carry all your fly stuff with you.
