2016 National Park Centennial Stamps
2016 is the 100th Anniversary of the National Park Service. To honor the benchmark, the Passport program introduced the Centennial stamps. Because of this, we have revisited some parks we have been to while in the area this year to collect the special stamps. The first park we visited in 2016, Death Valley, did not have their stamps yet. To date, we have collected 58 stamps as of 9/18/16. Our total to date is 63 actual stamps (had 2 more on loose paper but lost them - Zion and Great Basin NP).
