A lot of states are starting to do it that way. Nevada does but their kicker is that if you want a bonus point you have to pay, if you don't want a point then you don't have to. In Utah you have to purchase a license but if you work it right you only need to purchase one ever two years since the life of the license is 365 days from when you purchase it.
I go to Arizona every year to hunt javelina so I have the license and then I have been buying a bonus point for deer every year for $7.50 but that looks like it is going to change next year since they are revamping the system.
Here is a very handy and effective device I use to dispense corn with - but it could also be used to dispense any other seed or deer feed.
I had an old feeder that had a failed motor... I made a set of brackets to attach the feeder to the rear of the 4 wheeler - the lower one encircles the feeder and has a forward section with holes drilled in the outer ends of the bracket... these holes align with two 5/16" bolts that drilled into the rack of the 4 wheeler.
The upper bracket is an "L" shaped...
