In in Fort Collins and yeah, it's still winter here at elevation; there's a storm on the way now, actually. Going into the hills there's still a lot of snow, so you'll deal with a good bit of melt and washouts, but there are trails that are opening, so there will be areas for you to check out.
You can use resources like
Colorado Trail Explorer (COTREX) to give you a good idea on statuses, etc.
If you're somewhere around Denver or Fort Collins area, let me know. There's a few of us that go wheeling frequently and might be able to show ya a couple of places on a weekend.
