Winter trees: last chance?

I'm hoping this is my last winter trees post for this season, as surely spring is just a week or two away, right?

A need to stretch my legs let me discover these wonderful trees at a rest area somewhere between Springfield (Illinois) and St. Louis. Mainly sycamores, which are probably the best trees to see around here in the sunlight against a blue late winter sky.

I started snapping photos because of this oak that was just covered with galls:

Have you ever seen so many galls?

And that led my eye to one of the sycamores that still held seed pods -- not galls even though they look very similar:

Then it was just time spent enjoying the smooth bark of these beauties, their forms half-lit and half in shadow...

...and even the picnic table shelter's roof looked good to me:

Surely when it's time for my next trip the leaves will be visible, right?
