I did mine in the Canadian West. The Rockies taught me an awful about AC performance especially density altitude Jasper-Hinton 4000" amsl 35deg C, giving a density alt of 8000" in a 151hp C-172.
The prairies taught me a lot about navigating over featureless terrain. I also took the opportunity to land at a few busy fields like Vancouver International, Victoria, Edmonton City, Calgary International and Saskatoon.
Don't forget to enjoy it it's probably some of the best fun you'll have
