September 17, 2024, Tijuana River Estuary 17SEP2024

Flat trail good for walking or running. Very interesting to see the estuary surrounded by neighborhoods right on the US-Mexico border. Estuaries can already have a bit of a smell to them, and this river is polluted so can be a little ripe, but was ok today. Lots of birds, lizards, rabbits and ground squirrels.
