Err, "interesting" experience

Note: this didn't happen in an SVX, was in my dads audi..

So, I was in Upper michigan this weekend, hanging out and all. Yesterday, I went hiking along the pictured rocks with my dad. To get back to town we had to run about 20 miles on a rather rough dirt road. Just as we got to the pavement, the front left tire went, sidewall was just totally trashed. No big problem right? Toss on the spacesaver and we're set to go. So, we pull off the road, and start jacking the car. And the jack sinks into the sandy soil. Ok, well, no problem there, move the car onto the road and jack it up. And the jack sinks right *through* the asphalt, a good 3 inches down. I'm not sure if it was just because it was hot (~88 degrees), or just the content of the asphalt, but it was pretty amazing to see. In the end, somebody with a truck and a bigger jack stopped and we were able to get running on the spare (Good luck finding 205/55/16's on the shore of lake superior though..).

Anyways, it was just amazing to see the jack sink right into the road. Anybody had anything similar happen?
