I promised my nephew he could hold a snake!

So the kid is obsessed w/ snakes. Loves the snake house at Houston Zoo (closed) and I can’t seem to catch any garter snakes in my back yard. Repticon was bumped from July to October and I’m out of ideas. Nature Discovery Center in Bellaire has a milk snake and a corn snake (closed, I called. Yes, the website says open).

I’d like my nephew to hold a snake. He wants to hold a snake… What are my options?
