Why did the beetle grub cross the road?

I was going to write that this beetle grub was 5.25 to 5.5 cm but with ruler in hand I'd say its more like 7 cm: mondo!

Sorry I meant to look some more.
I couldn't find any pics online, and was going to look in some books but forgot! I hope its right, pics of the species will be helpful, so I'll try to ask around and try to find a key or description.

How big was it?
If it was fairly large, it may be Dynastes granti

Thats Dynastes tytyus but they're similar.

i'll bet you're on the right track
My 10-lined June Beetle idea would be a baby compared to this :)

That was another one I thought of though :)
They're decently large as well.

looks pretty big
Did you get a measurement of it? Looks pretty big and bulky. The shape looks like a scarab grub of some kind to me. I wonder if it might be a Ten-lined June Beetle grub or something like that.
EDIT - actually, lately I have seen some grubs out on sidewalks recently too.
