Indianola/ Port Lavaca/ Port O'Connor area?

My dad and I are going to be in Indianola near Powderhorn Lake this weekend trying to find a lot that my grandfather owns. Grandfather bought it in '52 and no one has been down there by it in 30 years. So we are trying to figure out what it is and where it is so we will need a place to watch the game somewhere near there.

Anyone have any suggestions or ideas?

Thanks in Advance.
