Rich, there is no fee now but there is talk of imposing a small fee to cover administrative costs. There are other states that have a small fee for these senior "free" licenses so I guess they figure that maybe it would be good for Ct. too.
For you youngsters that are not there yet what is "free" is only the base license; tags like turkey, deer, etc. are regular price for seniors too. So Ct. is still an expensive place to fish and hunt even for oldtimers.
