There's a huge display on Duval Rd, between 183 & Mopac. Noticed it last night, but was going by too fast to appreciate it.
There is a timed-to-music display at the corner of Millwright and Woodland Village, but haven't been by at night to see it.
And for those who don't mind traveling a bit and what something a bit more old-fashioned, there's the Ledbetter Christmas Lane of Lights (
