Sat through
a webinar (usually a walking tour) of 5 Points - quite enjoyable.
Learned of a relatively new resource -
replications of Manhattan using computer tech.
$12 for an hour and a half by a 'licensed' (not sure why you need one) tour guide. Not that I'm a great tour guide, but I think I've done a passable job as an unlicensed one during our Urban Hikes.
