What do I take pictures of?

I live in Cleveland, Ohio. Think what you may but its not that bad

My problem is this, when the weather is terrible or ugly, what do I take pictures of?

I love shooting outdoors and have no issues going out in the snow. However, right now, we are in the midst of a "heat wave". Its going to be in the 50's this weekend, chance of rain, but more than that, leafless, snowless, brown and gray.

I'm off this weekend, have an itch to go out shooting but am a little lost with what to concentrate on in dreary weather and not ideal shooting conditions.

What do you shoot during the "ugly" times of year? Indoor ideas are welcome but looking mainly for some inspirations outside.

Thanks for the insight!
