Cold crashing outside
 
Since we're in the mid-upper 30s here, I'm thinking about utilizing the free "refridgeration". How long should I leave it outside and will the temp fluctuations matter? I mean fermentation is over so the yeast just need to drop...

I'd wait for an overcast day, throw it out there with a garbage can over it. Figure 1-2 days will be good. As long as the ambient is colder than the beer you are fine.

Yeah I'm definitely gonna protect it from UVs. I'm not looking for Corona here...

I've been cold crashing in the garage where it's a toasty 39F by the front doors. Sure, why not. Just don't forget about it overnight if it's going to 20F.

In fact, I've been serving two beers out of picnic taps out there too. 7 kegs pouring right in time for playoffs.. woot.

How long should I leave it outside? Are we talking hours or days here?

It doesn't matter unless you are going to bottle it. You can even "lager" it in the bottle if you are.

Funny - I just did this last batch. Here it's low 40's during the day, just above freezing at night. Worked great. I just threw a towel around the cboy to protect the beer from UV.

A couple days will give it time to settle, but overnight will be enough to cool it.

I've always let it sit for at least 3 days in the cold, but I think the very act of getting it down in the 30's is benefitial over not doing it at all.

Up here in the Great White North
 
I've been crash cooling all my brews for 2 or three days in my unheated attached shed and have yet to have problems with freezing... in glass carboys, but not directly on the cement floor.

This weekend temps will be dropping below zero, so I'll probably move any liquids into the unheated front hallway, where temps have been right around 40-45 since December.

YMMV
