I have went to the parade a few times since it moved to the Havlock location. Parking on the streets near the route will not be an issue if this year is the same as recent years I have attended.
THe Shriners are a good organisation with a worthy cause that they support. Not a Shriner here saying that either. IF you are in Lincoln for the Shrine game you should consider going to the parade to show support for their organisation and causes.
