Thank you to all who made the 2017 Junior Market Sale happen. Our 4-H members, as well as FFA members, appreciate the opportunity to show their best animal one more time at our annual Auction. The generous support from our community and businesses goes beyond thank-you. Without your support, we wouldn’t be able to offer our members the opportunity to sell the best of their best.

2018 4-H and FFA members, the buyers’ list will be available in the Extension Office as soon after the sale as possible. Please stop in or call for the name and address of your animal’s buyer. Thank you notes are due September 14th.

Outstanding Volunteers

It takes a village to raise a 4-H project…and many times, the people in that village are your leaders and organizational leaders who give countless hours of their time to help our 4-H members succeed. Was there an outstanding volunteer in your life over the past year?

Nominations for the following awards open on September 1 and close on October 1. Nominations must be returned to the Boulder County Extension Office by September 21, 2018, and will be submitted to CSU in one packet. For more information, review the application form for each award.
