XXX - not what you think

XXX = 30  which is the symbol used for the 30 days of april.  i signed the pledge for 30 days of biking in april. last year got 20 out of 30 - hope to do better this year, - around the block,, in the gym, on a trainer counts.  good way to get legs moving and primed for the Falls Duathlon on the 29th.
