Don't get me wrong, Poblo is great after work fun when it's big AND I've paddled in more gross urban settings (hole brothers on the Black in Watertown NY is disgusting...but a great hole
Slipped on a used rubber taking out once. It may even be slightly less gross than Confluenza) BUT it stinks like fuel, is in a ditch and homeless people do live in the trees. Got a few ear infections from the water, too. When I go there afterwork my wife comes to meet me from CSU Pueblo and I set her up on a blanket with the dog and a cooler of brews and she watches me dick around. I put her in the shade by the trees above #1/2/3 area when it's hot and there's always a tent there with laundry hung up, etc. I can only assume some vagrant has taken up residence...which is sweet I think and adds to the...uh....ambiance.
FWIW, the mural is bitchin and the ditch would be much less tolerable without it. A huge Bob Marley laughs as you play and some creepy angel thing has a nice set of tits.
The bottom line is that at flows over a grand it's great fun and at flows down to maybe 700 it's worth a drive from Condo Springs, the dryest town in the world.
