I woke up to a text from my mom, "Your dad did see the website [Obon 2015]. He still wants to research more; doesn't want someone to take the flag. He is not very trusting, ugh!!!" She ended with the little caveat, "You can do what you want." A classic case of 'if dad says no, ask mom'. Although in this case I didn't ask my mom. She just gave me the go ahead on her own.
Her thumbs up was good enough for me, so I've reached out to Obon 2015, Northwestern University and the Field Museum. I've already gotten one response from someone at Northwestern University. People are amazing.
In the mean time, I'm going to keep sending emails and calling until I can get some responses.
