I agree, different sizes, say 2 more, a medium and a large would be great.

i AGREE. Bigger is almost always better.. I use hitches for my larger flyers protected by plants, on a floating platform and another domed platform for the rest of the flyers; However i spend half my time gathering up the strays when they drop through or just walk through, when on wander and i'm away. I like a large field of wandering dinos and they always have babies around for me to greet and accept. I've tried stopping all at once with a whistle but the is not very effective. I'm going t to look it over and see just how big I might be able to make it. thanks
