Hi Dave. Thanks for asking.
The trip I really want to be doing and that i first thought about was LA-Vegas-Zion-Bryce-Moab-Denver. Which is fine for me. But, then I read about the roads to Denver and maybe snow so I thought about getting to Vegas, and doing the loop, maybe to zion, bryce and moab and then getting back to Vegas.
I friend of mine was talking to me about Sequioa NP, and that got me wanting to go there too. But as you say, the less places you go, the better so i can get to know more. Still want to go though.
Would like to saty in park lodges and take small hikes and really get the feeling of driving around but also to sleep and wake up in these magical places. Do not want to be on the road all the time. Just enjoy as much as we can without overdoing it in 10 days.
