How Big is My Buck?

The boys were getting frisky this morning... Wouldn't even let me into the park. Tried to get some good shots of their horns, but they wouldn't get too close after I positioned myself somewhere other between them and the doe.

Just to be clear - this was my not my child chasing the buck. It's a frisky male Weimaraner we see most mornings.

Here's another pic from down the street... have no idea if it's the same guy...
