If I already bought a deer tag

From page 112 in the 2014 big game proclamations: Exchanging Deer or Elk Tags: Hunters may exchange general season elk tags for use in another zone at any Fish and Game office. Deer hunters may exchange a regular season deer tag for a white-tailed deer tag or a white-tailed deer tag for a regular season deer tag at any Fish and Game office. The exchange must be completed before the first hunt opening date of the tag you currently possess. For elk general seasons with a tag quota, exchange must be made before the quota has been met. An exchange fee of $3.75 will be charged. If you hold a valid general season big game tag and draw a tag in the second drawing the exchange must occur prior to the opening hunt date for the tag you currently hold.
