Yes, there are 3rd season OTC. Same as 2nd season, 5 day gap between 2nd and 3rd. More of locals and Californians season. Out of staters generally prefer 1st (limited) and 2nd (OTC) due to milder weather.
I hunt 3rd when I can but most non resident hunters from East of Colorado skip the 4th season because it clashes with the deer rifle seasons in the Eastern states.
