This morning it feels like I was ridden hard and put away wet- I've got mild aches and pains everywhere!
On the plus side I've been "boosted"!! 
If you remember I lost my original CDC card and was having trouble getting a replacement. My Pfizer booster shot along with shots #1 and #2 are all recorded on my new CDC card (and in my yellow WHO International shot record).
Have card, ready to travel.
'Only' 165 days until Jordan & Egypt!
