If you want to see an owl, rather than just hear them, you have a couple options that are easier.
This year, with the ongoing irruption, Snowy Owl has to be the top choice. They perch out in the open, either on the ground, fence posts, roofs, silos etc. As has been mentioned on anther thread, eBird is a good resource to find out where they are being seen.
Another easier owl to see is the Short-eared Owl. Being crepuscular, they are often easy to find hunting in the early morning or late evening. On cloudy days I have even seen them in the middle of the day. Again, check eBird for locations. You will also often find them hunting in areas that are frequented by Northern Harriers. They cruise low over grassy fields and marshy areas when they hunt.
If you are out birding and hear crows or jays mobbing something, always check it out. Typically it will be a hawk, but occasionally you will find them harassing an owl. This technique worked for me on a recent Christmas Bird Count when we found two Long-eared Owls.
For most owl species I am satisfied with just hearing them. Often if you try to find them you will end up flushing them and possibly exposing them to harassment by corvids.
