Will they close on Friday if it is raining? There is a 70 percent chance of thunderstorms that day and my Boy Scout troop was planning to come see the light display.

No they do not close. The only time is when there's lightning and a concern for safety. I had a friend of mine who was a meteorologist and he said he loved his job because he could be wrong all the time and keep it. There are no three-day forecast. The weather changes every 20 minutes. That's why he camps out in front of the Doppler radar.

That will be a last minute decision. But the lights are on rain or shine
