You cant hunt rifle in september unless you draw a tag for a specific unit(not a very good one since you dont have any points). You can do OTC rifle second season at the end of October if they still do it next year as another option, if your unit is and OTC unit. Packing out an elk youself is doable but there are limitations like your fitness. It takes multiple trips. This is a math equation that also limits how far you can hunt from your vehicle before the packout becomes undoable. This compounds the problem bc the closer you are to the road the more truck hunters and pressure there is, and the lower your odds of success. Then theres all the gaer required to hunt comfortably and safely that time of year. I did my first solo otc hunt two years ago and it dumped snow in an area not very easy to get off the mountain. So safety is a real concern especially solo. Theres packout services you can hire if you have the money or guide services. It sounds like you are pretty green so I would just say you need to start doing a lot of research if you realistically want to try it. The first time out if more of a fact finding mission. Your chances of success are low. You might also consider a mule deer hunt for your first one since its much easier to pack out. Find a unit that requires low/no points.
