Santa Monica Public Works personnel clean-up a Hazardous Materials Spill on Olympic Dr., between Main St. AND 4th St. on Tuesday, April 9, 2013. A truck allegedly from the Tonga Park construction site (across from Santa Monica City Hall) spilled its hydraulic fluid on Olympic Dr., from Main St. to 4th St. It does not appear that any of the fluid has reached the storm drains.

Josh Beaudoin from Gibbon Slackline and  Santa Monica maintenance employees install a new “slackline” park  at Muscle beach  on Monday, April 8, 2013. (this may be the first public slackline park in California?)

Made nationally famous by the Gibbon Slackline Team, who performed alongside Madonna at the 2012 Superbowl, slacklining is an emerging sport that challenges the participant to balance along a dynamic surface known as a slackline. Set up is usually low to the ground with trees serving as anchor points.

In addition to being a sport of its own, slacklining is also popular as a training tool for a variety of athletes. As it can help improve core strength, balance, and reaction time, slacklining is common with climbers, cyclists and other athletes. However, balancing on the slackline is also a fun and mentally stimulating activity for all ages.

The park at muscle beach utilizes a myriad of poles secured into the ground as anchor points for the slacklines. This allows for many different configurations and line lengths.

Andrew Greger drills the first wooden leaf onto John Muir Elementary School's ‘Giving Tree’ during the monthly PTA Art and Antique Fair on Saturday, April 6, 2013. The unique hand-made 10 ft tall plywood tree, created and built by the parents and children of John Muir Elementary is erected at the entrance of the school. Each donor will have a leaf with their name placed on the branches of the tree in recognition of their support. The Annual Giving Campaign was started to help raise funds for the school’s art, science, technology and music programs. It also helps fund field trips, reading specialists and basic school supplies. The school hopes the tree will "bloom" with support this Spring. Any donations can be made via Paypal on the John Muir website www.myjohnmuir.org or mailed or dropped off to the school at 2526 Sixth Street, Santa Monica, CA 90405.
