Mid-day stroll in the Arboretum?

I've been meaning to visit the Arnold Arboretum for a while now, so I'm kidnapping my brother and planning a stroll this coming Monday. Anyone else interested?

My current thought is I'll meet up with folks down at the Forest Hills station on the Orange Line, and around 10am start heading for the trees. Let me know if you're interested so I know to wait for you. It's supposed to get pretty warm, so bring water :-)

[Edit: timing change, ->10am]
