Get out early, real early. Use good glass. Watch the meadows, they're often after grass in the spring. Also after winter-kill deer carcasses.
If it's hot, take a nap mid-day, then be out again from say mid/late afternoon until dark. Glass until you can't see anymore, but be wary of taking a shot if it's about to get full dark - unless you want to track a wounded bear into a thicket at night...
Best of luck, it can be a lot of fun. Where are you headed?
