Collect up any photos or videos from the past years you have coached and make a DVD. I use iMovie for Macs each year when I make mine. Windows Movie Maker is also a great program if you're a Windows user. Both programs are easy to use and you can add in music, transitions, words and credits.
I think both you and your team will benefit from this! Anytime you find yourselves missing one another, you can pop in the DVD and relive the memories. If you find yourself having trouble, I would be more than happy to help you out or troubleshoot your problems.
Thank you for serving our country. Your team should be proud to have such an admirable coach.
