If you go real fast, you can catch air. =D
This spot reminds me of when I was a kid and A LOT of the arroyos in Albuquerque did not have bridges and we would drive fast through them to catch air. During the monsoons they would fill up and we would have to drive aound to one with a bridge. Then they eventually built bridges over all of them.
Additionally, in Lake Havasu AZ, they had "washes". I would visit my aunt with her two young children there. She had taken the middle seats of her mini van out and when she came upon a wash she would pull over, let her kids unbuckle, then wait for no traffic and speed to and through the wash and send the kids FLYING through the mini van as she caught air through the dip of the wash.
Ahh the good times.
Ayway, we have been down this road many, many times. This dip never gets old and is our favorite part of the drive. So I thought I would place a cache here. Pretty classic.
