This was taken on northbound I-15 near the Cajon Pass back in April. It's a towering inferno of Mega-RV (a Beaver Patriot Thunder) plus tow-hitched Hummer. This is like $500k+ worth of vehicle going up in toxic smoke. You could see the coal-black smoke plume for miles. No fire trucks had arrived yet as I held up my camera and prayed it didn't blow up while I passed.
