Large and loud, it's Monster Jam

Watch sports drivers compete, career, and crush stuff with their 12-foot-tall, five-ton, high-powered trucks Friday and Saturday at Monster Jam at the Wells Fargo Center.

Motorsports drivers will perform freestyle extravaganzas head-to-head, jumping sky-high over obstacles including trucks, vans, boats, cars, and buses in their decked-out, characterized monster vehicles. There will be wheelies, pirouettes, and lots of demolition.

The popular Candice Jolly (check out her crazy socks) will drive her Monster Mutt Dalmatian truck, and 2012 Monster Jam champion Bari Musawwir - the first and only African American to compete in the sport - will show off his skills driving the popular Spider-Man Truck. Other truck-and-driver teams include the Grave Digger, driven by Dennis Anderson; Scott Buetow in the Team Hot Wheels Firestorm; and Alex Blackwell ramping up the Captain's Curse. Black Stallion will be navigated by Mike Vaters, whose son Mike Vaters II will drive the state-of-the-art custom-made Overkill Evolution.

There will be a preshow pit party at 11 a.m. Saturday for those want to see the trucks up close, meet the drivers, and get autographs.

Kids can have a jazzy Saturday morning at PNC Grow Up Great's Hot Jazz With Drew Nugent, a free event at the Kimmel Center for Performing Arts.

During the hour-long interactive session, participants can learn about America's own art form and its musical variations ranging from swing to blues and other styles. They can see instruments and even join the band.

This kiddie journey into jazz is suitable for ages 3-5.

Enjoy seasonal activities from 10 a.m. to 3 p.m. Saturday and Sunday at Morris Arboretum's Fall Festival.

Make your own scarecrow, judge the 30 on display, paint pumpkins, and savor free apple tastings. From noon to 3 both days, visitors can meet the animals from Norristown's Elmwood Park Zoo and help make a LEGO version of the arboretum's own Morris the Merrie Little Owl with the teen group ColonialLUG (LEGO users group).
