I've seen a couple mossies so far but I always carry my binocs. It sure helps this time of year. When they are just starting to sprout a new battle gear it's hard for my eyes to pick up without my 2nd. specs.. Sure is fun to see them early on in the new cycle. I find myself paying real particular attention to the entire buck. Once I get to really observe the entire animal it helps me later to differentiate how a particular buck is forming up, so to speak.
