I am really afraid that the outer center camp road ("Feedback Loop" in 05 and "Wheel of Fortune" in 06) will be "Circle of Life"
It's too obvious, but would also be too reminiscent of Disney animated musicals.
My nerdier side is kinda hoping the Avenues have another non alphabetical system like the planets a few years ago.
Domain
Kingdom
Phylum
Class
Order
Family

If needed: Subspecies
If it is names of plants, let's hope its one's rarely found on the grids of america's towns and cities (no Cherry, Elm, etc.).
Algae (or Agave)
Bamboo (or Baobab)
Cactus (or Catnip)
Dandelion
Edelweiss
Flytrap (or Fennel)
Guava
Hemlock
Iris
Kudzu for the outer center camp road (or Olive Wreath)
From listing of "alternate" species from the USDA Natural Resources Conservation Service
Anise (herb that flavors Ouzo and other booze)
Bok Choy
Cilantro (or Carob)
Dill
Elderberry
Fig
Gourd or Ginseng
Hops or Hemp (yes its in there)
and Onion for the loop road
Or for local flavor, here's a list, drawn specifically from the list of endangered plant species in Nevada (generally the common name of the genus)
