Nope not BP they are opportunistic and ambush feeders spending they spend 80% to 90% of their time hiding in termite mounts just to ambush their prey at the entrance of said mount, they occasionally move to another nearby mount.Snakes in the wild still have to spend much time travelling for food
The only benefit will be for you, to show off, there is no benefit for the animal it is actually stressful (stress can lead to health issues), additionally over the last 10+ years snake keepers have been under tremendous scrutiny in the US (and if it happens here is can happen anywhere), with law makers trying to ban snakes, passing new laws in that effect, the people you will meet at the park will not likely perceive a snake as a good thing, do not become one of those giving the other side ammunition to push laws. You want to take you snake outside do it in your backyard do not expose the general public to it, there are enough bad headlines.We live mins from 2 parks but it's not hot enough for me to take him out for his first outing to the park. Altho I can't wait for that!
