- 49N: that’s as far north as you can go outside of Alaska or Minnesota (I have been to MN, but not the bit north of the 49th)
- ~29.9N: at New Orleans, not along the Gulf coast, though I have also been to the Gulf itself slightly north of there.
- ~74.6W: in an Atlantic coast state, but not all the way to the coast.
- ~123.8W: to the Pacific Ocean
