First surge I've seen in 3 weeks! It was only $1.50, but it was a surge! I was smack dab in the middle of it. I waited for 10 minutes and NO PINGS! WTF! Right after it went away, I get a ping, I still got the $1.50, but that was it. The next 3 trips were back to back, but no sure. I don't understand this surge stuff. What triggers it? I thought it was more demand than supply, but when I don't get a ping, I makes me go hmmmmm.
