One of the most coveted prizes in golf is up for grabs in Delaware County.
The first round of the U.S. Open Championship got underway briefly Thursday morning before the rains came.
Gates opened to spectators at 6 a.m. and the sun was fighting to get through the clouds.
Despite that, many fans knew what was on the way. You could see almost every person carrying an umbrella or wearing a rain coat.
"Lots of layers, lots of rain protection," said Barry Crell of Wilmington, Del.
"Rain boots, rain jacket, umbrellas are like the only way, change of shoes, anything!" exclaimed twins Morgan and Meghan Gibbons, from Vorhees, N.J. They are actually volunteering at the U.S. Open, working in the merchandise tents.
One man, Zach Cerra, was prepared after he learned his lesson from getting soaked at the British Open last year.
As he went through a small bag he was carrying, he said, "Towel, ponchos, nice rain coats for when the sky opens up. Hopefully not, but gotta come prepared."
There were a few who weren't as prepared.
One man, Scott, said, "Look for me at the Trophy Club." His friend, Joe, explained, "It's a tented area that is over at Haverford College. There are concessions, all kinds of places to sit, lots of TVs to keep updated and it'll hopefully keep us dry."
He would need that hope because as the morning went on and the golfers teed off starting at 6:45 a.m., the skies got darker and darker.
Then, at 8:36 a.m., play was suspended due to severe weather moving in. Shortly after, rain started pouring, thunder started slamming, and lightning started flashing.
The practice areas re-opened just after 11 a.m. and play is set to resume at 12:10 p.m., with afternoon tee times 3 hours and 34 minutes behind schedule.
