Definitely a big time ridge signal out there for the western half of the country, but as of now the EPS keeps the PNW fairly comfortable - though certainly warmer than recently. I don't like my odds here.
Nothing annoys me more than people going offroad without deflating their tyres. If you drive on soft sand or a salt flat with 35 psi tyre pressure, there's a 100% chance you will get stuck. Saw a bunch of car stuck in a salt flat.
Deflate to 15-18 psi then go offroad.
