Hexanimo

You’ll hate me for this, but I semi-frequently write my extended no as nuuuuu to specifically target a rhymes-with-moo read.

That’s very close to spider in Spanish, araña.

West Coast perspective:

• Siskiyou Pass is both the biggest change in elevation and steepest grade on I-5
• the grass is literally greener on the OR side. CA is known for its golden grass that is much dryer (hence the Golden Gate. As a child I was disappointed that it is painted orange and not gold)
• Agricultural Inspection Station mentioned in another comment (only when traveling into CA)
• not a huge cultural difference between upper NorCal and Southern Oregon though

Further north…

• crossing the Columbia, the biggest river in the region, also has one of only several interstate draw bridges in the US. Prepare to be stuck in traffic if you’re remotely close to rush hour
• No sales tax in OR means there are large malls immediately off the first OR exits. Likewise there isn’t a single Best Buy in Vancouver because everyone drives across the river to dodge sales tax for big ticket items

The inspection station I pass by is still there, but it’s been literal years since I’ve actually been stopped or even seen it manned. I don’t make the trip regularly and have always been in a sedan, so maybe I’ve just been lucky. Though my guess is that funding cuts have hit them badly.
