Arnold Schwarzenegger took a ride on his motorcycle Monday afternoon in Malibu, Calif. The 63-year-old wore a black helmet and leather jacket as he drove through town.

Meanwhile, the former governor’s estranged wife, Maria Shriver, tweeted her appreciation for veterans and their families on Memorial Day. “This weekend, I’m thinking of all who gave their life, and all the families who lost a loved one, in service to this great country,” she wrote. “You have our deepest gratitude and respect. God bless.”

The 55-year-old even shared some words of wisdom with her followers. “My daughter once gave me a great Plato quote that said, ‘Be kind, for everyone you meet is fighting a hard battle.’ I love that. So true.”

She added: “We don’t know what is going on inside of most people. On this Memorial Day, when so many are grieving in obscurity or silence, let’s keep that in mind.”

Schwarzenegger and Shriver’s oldest son, Patrick, enjoyed some quality time at the family’s Malibu house on Saturday, according to his Twitter page. On Monday afternoon, the 17-year-old wrote he was “going to the big Apple — New York City!”

In addition to Patrick, Shriver and Schwarzenegger have three children together: Katherine, 21, Christina, 19 and Christopher, 13

I have written many times about Arnold Schwarzenegger before. Here are just a few of the times:1. President Reagan having a photo taken with Arnold Schwarzenegger at the Republican National Convention in Dallas, Texas. 8/23/84.2.Here is a video clip of Arnold Schwarzenegger using an Airlight
Broom as a prop for “cleaning house” in the California Recall
Election as seen on CNN, ABC, CBS, NBC, ect in 2003. The
Airlight Broom is manufactured by Little Rock Broom Works.3. I heard John Fund of the Wall Street Journal speak in Little Rock on April 27, 2011 and in his speech he mentioned the struggle that Arnold Schwarzenegger had with the envirnomentalists in California. I took time to repeat a lot of the facts about that in my blog post that day.4. At that same luncheon on April 27th that I mentioned earlier, one subject that John Fund brought up was the red tape that Arnold Schwarzenegger had to deal with in California. I wrote about that too.5. St. James Palace has confirmed  that Kate Middleton and Prince William – or, more officially, the Duke and Duchess of Cambridge – will be visiting California from July 8-10 this summer. Former Governor Arnold Schwarzenegger is expected to greet the Royals as they touch down.6. Which is better for setting up a business: California or Texas? Arnold Schwarzenegger is mentioned in this post too.7. Arnold Schwarzenegger is fond of quoting Milton Friedman but he rejected fiscal conservative idea to cut spending.8. Pictures of Arnold Schwarzenegger and Maria Shriver through the years. Video clip of them at Ronald Reagan’s funeral.
