I'm just getting to work in the mornings and I'll take our Greenway unless it's flooded, muddy, frozen or closed due to construction. Alternate is the shortest direct route. Depressingly predictable but the Greenway makes up for that in the morning, deserted, non-stop through a narrow vestige of natural forest.
Coming home I'm more varied, but still formulaic. Skip the forest when there are storm winds, branch out when the weather is nice and the sun is shining. One way for hills, another for sprint intervals, a different route for just a longer ride.
