Around here, it is mostly watching for silly squirrels, I do NOT radically deviate from my path to avoid Crabs or Lizards (small ones anyways)...Gopher Tortoises I DO avoid as well as Alligators (have YET to have to dodge one of those on my bike...but HAVE in my car...about a 6 footer). Read an article about a cyclist up north of us that got run over by a BEAR! The bear kept going, the cyclist was somewhat messed up! CRITTERS!!!!
