Hey Marco:
Anytime on either day would be fine. For convenience, we should
probably meet in my office where we can look at the sketches and
discuss options. Because I like to walk around in the morning and
check the state of things, I'd recommend 10:00 AM on Monday,
or after my Senior Staff Meeting on Tuesday (10:30 ish).
