Look for concentrations of rubs. This indicates a buck or multiple bucks spent a good deal of time there. Also follow rub lines, they are easy to see now, and they can lead you to a bucks core bedding area.

Scrapes are easy to see now too. I don't imagine they are covered with snow in LA. They can also show you a bucks travel pattern and places you might intercept him next year.

With the leaves off of the trees you can also see the topography of the woods better too. Look for funnels that restrict deer movement. Old fences, ditches, steep hills that the deer walk around, creek crossings, anything that will alter the travel pattern and bunch the deer up in a small area that you can cover with your bow.

Happy scouting, this is the best time of the year to scout in my opinion. And you won't be disturbing the deer you are hunting.
