Cricket Songs in Bankers Hill
The chirping of crickets tells us the warmer weather of summer is well on its way. Their plaintive pleadings for mates are heard wherever bits of seminatural scenery cut across the urban tapestry of San Diego. Try the Spruce Street suspension footbridge, west of Balboa Park between Front and Brant streets. From the swaying deck of the 70-foot-high bridge you can admire a canyon filled with green and gold grasses, nasturtiums, and eucalyptus, pepper, and palm trees. Sound effects begin by midafternoon.
