Hello to all from snowy Asheville, NC

I bought a Petrol camera bag (W/PRCDV) recently and it came with a rain cover (PRC-DV RAINCOVER F/PD-170). I have looked this thing over very carefully and cannot figure out how to put this cover on. Does anyone have any experience fitting all the various pockets over the viewfinder, mike, etc.?

I was hoping to use this in the snow today. Also, does the mike still work with the rain cover on?

Thanks in advance.

Richard
