I can help you with J Bar H, As of yesterday, she has one drop camp available for the third season next year. (2019) If you want it, I would book it quickly. She normally is booked solid. Her drop camps are all in very good areas and she has a very high success rate. Her camps are also first rate. You may want to get on her wait list if you miss it since sometimes people have to cancel their trip. I have hunted with her for many years and can assure you that she is a true lady and her staff is top notch. Sadddlesore and Sharecropper also know her personally so you could PM them for additional information.
As far as hunting during the third season in area 24, it will depend on where in 24 and what the weather is doing. Many years the snow is very bad during the third season and the elk have moved lower. But if the snow holds off, that can be a great area. Good luck and have a great hunt wherever you land.
