This is such a good write-up. Slowly builds on top of what I would consider the very basics of location terms while adding complexity in a digestible way. Excel

This is such a good write-up. Slowly builds on top of what I would consider the very basics of location terms while adding complexity in a digestible way. Excellent illustrations, great examples, and overall an informative teaching tone... It is worth every minute you spend reading it (took me over 60 to get through it and I feel like I did skim a little towards the end)
