The easiest place to park is in the lot on the South side of Centennial High School (on the left side of the building if you are facing the building.
To get there, enter the bus loop (on the south side of the building) and make an immediate left onto a drive that passes through a gate. It looks as though this is an illegal turn, but it is not.
This parking lot is hidden from the road, so it may not be easy to find. If you have trouble parking, park in any lot, enter the building, and then follow the Columbia Insight Meditation Class signs to room 406.
Chairs are always provided or you may bring meditation cushions for sitting on the floor (tile).
