This weekend you might want to consider taking advantage of a once in a lifetime opportunity: Santa Monica Pier's Pacific Park Ferris Wheel is on ebay's auction block and at press it was going for a mere $50,000. If you don't have the liquid assets to purchase this L.A. icon, catch one of your final glimpses of it during Sunday's Earth Day Celebration: the Green Apple Festival.

On stage this weekend, the L.A. Opera presents Plácido Domingo's 40th Anniversary Gala performance and opera superstar Bryn Terfel. This also is the last weekend to see MASK at the Pasadena Playhouse. If speed is your thing, catch the 34th annual Toyota Grand Prix of Long Beach.

Let WhereLA.com be your guide to these and more of this weekend's entertainment opportunities. Check out our weekly Weekend Roundup.
