There are two things I have not witnessed since moving to Arizona, that everyone claims exists... but I never seem to see.
1. Scorpions. I have yet to see a single live (or dead for that matter) since moving to AZ 6 years ago.
2. Haboobs/Sandstorms that are so bad, that you really *DO* need to pull over for because of lost visibility. I've driven in rain storms that compromised my visibility *MUCH* worse than *ANY* haboob I've seen so far. Those aforementioned rainstorms *NEVER* have "Pull aside, stay alive" notifications or advice,... inspite the fact that water both more severely impacts visibility, but also increases stopping distance and increases the chances of accidents due to slippery surfaces. I've never witnessed a haboob where visibility was drastically reduced to less than recommended following distance.... they've never come close as far as I can remember.
I almost feel like the state takes these damn haboobs more seriously than they ought. I feel like haboobs are the most over-exaggerated weather phenomena we have in the state. I think you're way more likely to crash in the rain than in a typical dust storm. If I ever find myself in a dust storm that severely reduces my ability to see a beyond the 5 second rule... I will pull my own ass over.
Maybe I've just been lucky to either be at home whenever these storms happened, and never looked outside to see how bad it is. Maybe I'm just lucky that in my 6 years here in AZ, I've managed to avoid the 3S things Arizona has to offer (Scorpions, Snakes, and Severe Sandstorms).
