We saw the surgeon in Iowa City yesterday and surgery is scheduled for October 6th. We will have to go up on the 5th for Greg to get his covid test and then we will stay in a hotel for the night for surgery on Tuesday. The doctor is telling us the surgery will be 4-6 hours. Due to Covid they are only allowing one visitor per day, and only between the hours of 1pm and 5pm. 
Dr says as long as everything goes well with surgery and Greg is able to be up and walking he should only have to stay 2-3 days. I will be up there with him, just have to stay in the hotel as the house of hope at the hospital is closed due to covid too, but i will update as I can after his surgery.
Thank you all for your love and support!
