Took a couple of hours and fished the South Platte above the inlet to Chatfield yesterday. Got skunked! Was using an orange then later a tan scud with a dark grey midge dropped off the scuds. Started at my favorite hole near the gage and bridge, and worked my way downstream. Nothing. Walking back, I ran into someone who was pulling them out right and left from my favorite hole. He was using a san juan worm with a red disco midge dropped off the worm. Should have switched, didn't even think of something red.
