I've been fascinated for many years (particularly as a former History teacher) about the Aztec and Mayan cultures, and have been lucky enough to travel there from Australia in recent years.
I'd love to do a PhD thesis on some aspect of the planning revolving around these cultures, and have done a fair bit of reading of late. The only trouble is finding a particular aspect of significance to write about.
I'd really appreciate any ideas from you esteemed planners and colleagues out there on this one! Any help would be great...
