Safe to run and drive?

we drove a Honda up to Mammoth up 395 and we had to stop to check a misfire. We put 4 plugs in and away we went up 395. 10 minutes later the hood flies up, bows out around the windshield but doesnt break it! Knocks the rearview mirror clean off. We removed the hood, tossed it in the bushes and continued our journey. Get to within 5 miles off the Mammoth lakes exit and the road closed 5 minutes before we get there. White out conditions. CHP calls it closed for the entire weekend and we end up cutting across CA on some 2 lane road south of Bishop and went to Vegas instead.
