My best advice is to get tire liners, "slime", or some other type of protection from flat tires. This will not protect against all flats, but tire liners made a huge difference for me.
My first trip on the Katy Trail, I had about 8 flats. Got tire liners before my second Katy Trail trip, and had zero flats. It's a different trail, but both trails have similar thorns. Also avoid riding through the vegetation on the trail as much as possible to avoid the thorns.
Your local bike shop will have the liners and would probably be happy to install for you.
I hope I haven't jinxed myself by bragging about how flat-free I've been with the liners! :-)
