Populated the dropdown with only active locations, added a time picker, bound the checkbox state to the modal, fixed the issue of displaying the date correctly (I had to convert it to UTC in the server), added the delete activity feature, added the update activity feature. Made the update activity modal start with the currently selected location for the activity to update. The server side is bound, and I was able to test updateing the activities. I'm ready to move on to events first thing tomorrow morning!
