Our current map holds 394 US roster rows (pulled 2026-10-02); the official roster is at ahsgardening.org/wp-content/uploads/2026/09/AHS-Garden-Network-List-09.11.26.pdf.
Optional, per garden: some gardens apply a Local Visitor Exception and offer the benefit only to visitors whose membership card address is more than 90 miles away. AHS flags those gardens on its map; most don't use it.
