Re: important gear storage question
The upside of keeping your gear in the trunk is that you are ready to fish wherever you may be in your car. I live in San Francisco - so San Diego seems hot. I'd probably at least store leaders and tippet somewhere cooler.
Depending on your neighborhood and the $$$ factor of your car, you might want to keep the stuff inside. If you keep it in your car nobody will see you loading/unloading the gear except at the river.
