I can't say enough good things about the ladies who work at this SILT, CO. Post office, friendly, helpful & knowable are a few words that come to mind. However, the postal person that delivers our mail to our community mailboxes needs more training. On an average of 3 times a week (I kid you not) we get someone else's mail in our box, which we always hand deliver ourselves to the home address; and we get neighbors on our street who have also delivered to us some of our mail which was in their box. Today I get notice that an important package I had been waiting on had been delivered, but when I used the key that was in my box I get someone else' package. I now have to go out again after a long day at work and do the postal person's job AGAIN delivering their package and hope & pray that she has mine. Can you PLEASE get this person trained to do his/her job properly, this is U.S. Mail we are talking about, something not to be taken lightly. Thank you sincerely Stoney Ridge resident, Silt, CO.
