Ostensibly the world's only repository of neon art and artifacts, the Museum of Neon Art is the preeminent place to admire that stunning 1940s liquor store sign or bask in the glow of offbeat installations by artists who attended Burning Man. Moving lights and goofy sounds lend a playful feel to the galleries, attracting both kids and grown-up fans of American pop culture. Housed in an unassuming commercial space deep downtown, MONA also maintains extensive archives documenting the often-ephemeral art of the neon sign. Admission: Adults $5; children under 12 free; students/seniors $3.50. Admission is free on the second Thursday of every month from 5pm to 8pm.
