Meltdowns and going out

If he bolts that might not end well. 

I wouldn't want to be taken anywhere mid-meltdown except my own room, where that can purge itself safely.  I'm not sure anyone could move me anywhere easily. And nothing would calm it at that point. 

If you catch it in the rumbling stage anywhere away from the stressors, say the park, might.

On a Saturday when the weather is dry it is very likely to be fairly busy I think. Thanks 

That depends on how calm the park is, if it is crowded and noisy, then probably not.
