The theme of the XXXIV International Meeting on Fundamental Physics on April 27, 2006 was "From HERA and the TEVATRON to the LHC". At that meeting I presented four lectures on "Physics at the Tevatron". This is a summary of two lectures on "Physics at the Tevatron: IMFP06 IMFP08" presented at the XXXVI International Meeting on Fundamental Physics held in Baeza, Spain on February 4–8, 2008. These two lectures are an attempt to highlight what we have learned at the Tevatron since my lectures in 2006. I will also look back at the "old days" of Feynman–Field collider phenomenology.
