He's a perfect 10 mutt. I don't even need a leash. Loves everyone and everything and never disobeys. Makes a lot of yellow snow though. I cover it back up to keep my pack pristine. Snow is serious stuff.

He is good lookin!

Thanks for sharing!

10.1" for the storm in Clarksburg.  It's just dumping snow out there right now.  Went to measure snowpack in a place where there was still snow from earlier in the week and the ruler disappeared.  Time to use the tape measure...

das my measurement as of 6:15 is close to 11.2"  And it is snowing much harder now than few hours ago!  Unbelievable!

Were you not aware that this storm was going to change over?  It might have been mentioned once or twice.

 

 

Yes, I know that. I'm referring to the fact that many areas just to my west were previously sleet and now are snow, such as Centerville, Burke, etc.
