Compact mountain town 20 miles west of Boulder has heavy through traffic on SH-119 and SH-72 (Peak to Peak Highway). Somewhat tangled street layout is the reason for the 20 mph limit near the bizarre (traffic calming) traffic circle at the 6-way intersection that all orads pass through. They are looking especially for bewildered tourists driving motorhomes. Ironically, they seem to have used the revenue to build a new Tourist Welcome Center. Study the map before you get to Nederland, and prepare for very confusing signs-and an overeager constable. Automatic sign tells you how fast you are going as you approach town, which should be a warning!
