Whitewater Center - Tower 98 & Toilet bowl 

U.S. National Whitewater Center located in Charlotte NC. Here is a glimpse of the downhill portion of Tower 98 and Toilet Bowl. Both of these trails are black diamonds but was manageable by a beginner (Grandpa). Parking at the WWC is $5 unless you purchased a season pass.
The bike is a Specialized StumpJumper rented from the Bike Shop at the facility.
