18.3 is here and Amie said it was a ton of fun. I believe her. 
If muscle ups are not your jam, but you can double under and overhead squat the RX weight, you should do that. Once you get to the muscle ups, your open time will be over, but you can continue with a movement you CAN do like pull-ups to get a good workout in. Same thing with the pull-ups. If you go scaled, get to the pull-ups, record your tie break time and then kettlebell swing or jumping pull-up away! 
We will be leaving the gym at 4:30pm – caravanning our way up the hill to CrossFit Sonora. 
No afternoon classes tomorrow.
