Plunging into the cool waters of Biscayne Bay from the old Rickenbacker bridge (next to and below its replacement highway) is one trippy, exhilarating experience. When you just can't take another sweat bead from the summer swelter, can't tolerate the oozing burn meant for lobsters being cooked, then taking a dive is your solution. Liberating -- you're flying! -- and mind-blowing -- what if it's only two feet deep? -- the bridge free fall is the splash that refreshes. From the bridge you plummet about twelve feet into the sea, scaring hell out of any fish in the area. Time freezes, you feel gravity's mighty pull, bubbles surround you. Exhale, sink as far as your lungs allow. The yawp of the howling teens watching from the bridge is muffled, creating a psychedelic underwater soundscape. Nearby you hear the splash of another bridge jumper. You surface for air. You grin, no smile. No, you beam like a little kid catching his first fly ball. The sun bakes your marinated skin. You swim to the shoals at the foot of the bridge (sneakers while jumping are recommended) and run around to the ledge. A few more times and magically you are carefree, fresh, and feeling like the crazy kid you're behaving like.
