There's access to the south side of Boca, and both sides of Boynton. Large plugs or jigs on the outgoing tide would be my choice. Live bait is hard to present correctly with the current unless fishing from a boat, and that can be dicey as they're both so narrow. Traffic will be heavy this weekend. Apparently it plays havoc with the ecosystem and really mucks up the water.
Wild shiners are THE bait for big largemouths.
