I'm going to take the "baby steps" approach that everyone who always wants sunday hunting on private land only with bows typically take.
IMO - crossbows state wide is a baby step towards expanding hunting in general. You'll have people who can't pull a bow (too young or too old) that can get back into bow season without having to use a Lock-draw style accessory.
More hunters = more support.
Sunday hunting unfortunately will be the last thing we ever get in this state - so I'm ok taking what we can get and keep working towards the ultimate goal of sunday hunting.
