Name: Houston Zoo
Location: 1513 N. MacGregor (in Hermann Park).
Google Map location (map actually shows side entrance - use the entrance near the lake for better parking.
Website: HoustonZoo.org About: Great Zoo - special kids area, primate area, and more. An African area is under construction
Photog Friendly: Very photo friendly, and they allow tripods.
This is a great place to go, especially if you invest in one of their season passes (I've had one for the past couple of years). Pass holders also get private showings and early entrance (8 am) the first Saturday of each month.
Favourite time to go: Sunday Mornings - Show up at gate opening (9 am), and you'll find them feeding many of the critters, still cool in the summer, and no crowds until about 11 am.
