One of the simplest ways to do this would be to split the string. In my test, the field was returned in the following format:

POINT (-122.36 47.656 -122.343 47.656)

So a simple split would get you both. If this is something that you will use frequently, create a simple Inline function to do this for you:

I ended up making a stored proc to return the lat and long from the fields.  With the geography data type it wasn't stored as a string for me to split.
