The answer to the question below: it's a big ant hill.
No matter what you call it, I didn't want to get anywhere near it.
When I asked a lady about it she said it was ants and that it's alright to touch them -just don't poke a hole in it.
Yeah...I can see that...I wouldn't want someone a million times bigger than I am to poke a hole in my house either.
Just the thought of poking a hole in one of those gives me nightmares.
