Same reason I still carry a compass. Back up. I use phone with OnX and several other GPS apps, a handheld GPS as backup, and a compass as backup to the backup.
I was able to find Carbon County and Albany County road maps online from their county websites. I wish the news was better for me. I found several roads that are private that I was hoping were public.
So you might want to search for your particular county online.
If you know where you will be ahead of time, you can download maps while you have cell service. Then when you lose cell service you have to use your saved offline maps. Do it before you enter the spotty cell signal areas. This worked great for me in NW Colorado 2 years ago.
Can't speak for Elk and broadheads but I have put Ramcats through some wild hogs and lots of whitetails. Just be aware that they are 1 3/8" and may not fit your current quiver. I had to change quivers when I started shooting them about 10 years ago.
We routinely age whitetail deer meat down here in Florida in coolers. Keep the meat dry and don't let ice touch the meat. Garbage bags or big zip locks. Make sure meat cools before putting in plastic. I usually do 4 days to a week. Wild pigs as well.
