Funny you mention the logging trucks! I remember as a kid my folks took us on summer trips in the 25' foot motor home in the late 60s/early 70s. Up through California, oregon, and Washington into BC and Alberta a couple times and there were always a ton of trucks hauling logs, crazy like!
And speaking of arson, I heard just the other day that there's been people betting on brush fires, their occurrences, maybe durations, etc on those new "bet-on-anything" online gambling sites. Now that's just asking for arsonists!
