x2. Rover camping vs backpacking is one of the big divides. Honestly assess which direction you lean & you could save yourself a TON of money. Like anything else, you can spend far too much money on very expensive sleeping bags that don't add much value to your main usage.
The other big divide is EAST vs WEST. I remember,,,,as a kid growing up back east,,,camping with the old man. It was like,,,Ranger training. There were days & nights of Sturm und Drang. Always wet,,,often rainging,,,freakin' bugs out the yang! Mosquitos! The humidity & sweat in summer! The damp biting cold in winter. Your gear was always coated with rain or dew or frost or sweat. I'm scarred,,,
In Colo on the other hand, in comparison, I think camping is a big joke,,,in a good way. You can start a fire at will (the key is
not starting a fire,,lol). It rarely rains & is never damp. No bugs to speak of but the occasional spider or centipede. Hell, camping here in the summer you can pretty much just drink a few beers & lie down on the pine needles. ZZZzzzzzz
So anyway, if I was camping back east I would get a synthetic bag. If I was backpacking out west I would get a down bag that compresses to the size of a tootsie roll. If I was Rover camping I would get a big comfy square bag from Cabela's with a fat freakin' air matress & live large. If I was backpacking I would get the best foam pad I could buy & roll that sucker up. Yeah, it looks dorky,,,but I'm not a fan of Thermarests. Busted two of 'em over the past few yrs. Also, make sure you are comfortable sleeping in a mummy back before you go that direction. Many are not. There are square bags with comparable features.
Anyway, those are all my thoughts,,,I need to get a cup of coffee to get out of this stream-of-consiousness post.....cheers
