INDNR recently sent out a survey. It primarily was to gauge opinions on bringing back lifetime licenses, but also had an extensive section on deer management and seasons. It is open to all hunters, whether resident, on non-resident, and anyone interested in deer management. It concludes with a spot for comments, concerns, feedback, etc. (like, asking for a flintlock exclusive season). you must have an Access Indiana account so the survey link can be emailed to you. Here is the portal page.
