Murrow has their open house dates posted. Those are open to everyone and you don’t need a reservation:
Monday, October 22, 7pm - general open house
Monday November 5, 7pm - specialized programs open house
Murrow also does tours. Info will be posted on their homepage:
Sign ups for these aren’t announced in advance and they sell out SO FAST that I’ve found even if I’m at the site the moment info is posted, in the less than a minute it takes to send an email out to families, they tours are full. They’re generally during the school day and are small, which is why they sell out that fast. If you want to attend one of their tours I’d suggest checking their website somewhat obsessively.
