Inexpensive fun in Vancouver in the spring

I’ve been pondering about this for a while, as lately (even though I’ve had a fairly solid and steady income stream, I’m still buried in debt) I had been trying to find ways to have inexpensive fun with friends in Vancouver. Now that the winter seems to be behind us (hopefully! fingers crossed), it’s time to devise not-expensive, fun stuff. I thought of a few things that I’ve done that don’t cost much (e.g. bus fare, etc.)

– Hiking in Deep Cove and going for a walk along the beach in Panorama (North Vancouver).

– Going for a walk in Vancouver (there are lots of places, including the seawall).

– Attending the free exhibits at Vancouver Art Gallery (I seem to recall there are a few).

What else can you think of that can be done on the inexpensive? All suggestions most appreciated.
