Yeah must admit, with my nice walnut rifles, I don't really use them outside the range, and when it rains, that's the end of the day for me. I meticulously spit and polish those girls after every shoot.
My old marlin though - that's my truck gun - I've actually altered that gun quite a bit, and scratched the blueing in the process, its a bit of a monster these days, so I really don't mind if it gets knocked around anymore. That's what I take out into the field with me - it gets the job done.
