Trees at Epsom? (4)

Ross

I believe the answer is:

oaks

I'm a little stuck... Click here to teach me more about this clue!

'trees at epsom?' is the definition.
'oaks' can be an answer for 'trees' (I've seen this before). I am not certain of the 'at epsom?' bit.

'trees at epsom?' is the wordplay.
'trees' becomes 'oak'.
'at epsom?' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'oak'+'s'='OAKS'

Can you help me to learn more?

(Other definitions for oaks that I've seen before include "Acorn trees" , "material for shipbuilding" , "Trees of the genus Quercus" , "Soak up with trees" , "Hardwood trees" .)

I've seen this clue in the Evening Standard.
