Absolutely agree. The one thing you don't want to be doing is figuring out how to do a job when it's so cold you can't feel your hands, you're miles away from home, it's raining and the light is fading, and something is broken on your bike so you can't ride home until it's fixed.
Depending on where you are you could always call a taxi to take you home (or a friend with a big enough car) but that assumes you've got cellphone signal, a willing friend etc.
