Cart “pods” may be last year’s revolution, but this cluster, which caters to cyclists plying the Springwater Corridor and motorist refugees from 82nd, could become this year’s most happening “street” scene. A recent visit found a half-dozen carts, with more promised by summer’s height. The standout: Cascade Burger, where a self-professed lifelong vegetarian (!) grills an excellent half-pound of beef with superb fries and house-made ketchup. A trailer loaded with a big-screen TV also makes for fine Timbers viewing.
