Holy inventory, Batman!
My wife told me we were going to "Garden Ridge" and my reply was "we don't need garden supplies." I've never been more misinformed in my life. Driving up to this place gives you an idea of how huge it actually is. Then you walk inside and see it's even bigger. This is the largest collection of stuff (think suits of armor and 10' tall inflatable Halloween lawn ornaments.) There are endless aisles of the most random items you'll ever find in one place. Are you looking for a carpet? They have mountains of them. Need a throw pillow? Try searching through a dozen aisles. There must have been a sale on bar stools - they had hundreds.
You need to go here for the experience. Look for the recliners in the back of the store. They are a good way to break up the journey.
