Getting ready for a NP road trip

Matt and Karen, thanks for your books and the podcasts. Paul and I are getting ready to hit the road as we are vaccinated, recently retired, and in good health. We have been to 33 parks and will add 3 more to the list. Also, we plan to revisit 5 parks. The podcasts on Carlsbad and White Sands are super helpful.
