You will enjoy CO, just watch out for the redneck landowners
Colorado is a great place to boat, if you don't mind redneck landowners who think just because the river runs through it they own the damn water. Hook up with some locals, enjoy the Ark for your first season with a few trips thrown in to a couple of other fun places (Lake Fork of the Gunnison, Taylor, Taos Box (if it runs), upper Rio Grand (not hard but god is it beautiful back there) are all in your neck of the state. Lots of other fun stuff up north and out west. Just the places nearby should give you enough to last you a summer. Hell, the Ark alone could keep a III-IV boater happy for a summer. Granite/Pine Creek, Numbers, Fractions, Frog Rock, Bueni Play Park, Milk Run, Brown's Canyon, Salida Hole, Rincon, FIBARK, Cottonwood, Texas Creek, Pinnacle Rock, Parkdale and the Royal Gorge and your own play park right in Pueblo has everything you might want and maybe then some.
Welcome and have fun, be safe and register to vote, we need voting boaters to keep our rivers open and free.
