I have a National Parks Passport so I record the date(s) that I was there along with a stamp and, per the enclosed checklist, I have been to 70+ park properties. Some are National Parks, others are Memorials, or even National Recreational Areas, etc. Some are obviously better than others and being at one for an hour is enough and for some it requires multiple days to fully enjoy or even repeat visits.
Covid has allowed me to work from "home". So, in 2020 I visited Glen Canyon NRA, Grand Canyon NP, Petrified Forest NP, Pipe Spring NM, Sunset Crater Volcano NM, Tonto NM, Walnut Canyon NM, Wupatki NM, Buffalo NR, Fort Smith NHS, Pres. Clinton Birthplace, Pea Ridge NMP, Poverty Point NM, Aztec Ruins NM, Bandelier NM, Capulin Volcano NM, El Malpais NM, El Morro NM, Pecos NHP, Petroglyph NM, Mesa Verde NP, Arches NP, Bryce Canyon NP, Canyonlands NP, Zion NP, Grand Teton NP, Yellowstone NP, Abraham Lincoln NHP, Cumberland Gap NHP, Brices Cross Roads NBS, Natchez Trace NST, and Tupelo NB. Love me some National Parks and the great outdoors that many of them offer.
