I've been trying to do that…it's not as easy to reach the distinctive landmarks with a semi as with other vehicles, including RV's. All the really cool places have signs up that say "No Trucks" and it really bums me out.
I understand, though, because there are so many truck drivers who just throw their trash where ever they want instead of find a garbage can. And they pee on the ground rather than expend the extra energy to walk 75 feet into the bathroom. Trucker areas reek to an eye-watering level in hot areas because of this.
But I do try to find distinctive landmarks when I can...the little lake in Minnesota, the rock formation in Colorado, coastal trees in North Carolina....
I will try to find more landmarks I can access.
