The envelopes with the CO refunds are larger this year yet the outside wording on the envelope is not as obvious as to the contents. Might be easy to think is a miscellaneous mailing from CO Parks.
FYI...... if you applied for PP for different species, the checks are issued separately for each. I have already received my deer PP refund, and If it is anything like last year, I should be seeing my elk PP refund within the next few weeks.
