I have always been thinking that it would be exciting for hosts to have a common uniform (at least a shirt) similar to Royal Rangers ones or boy scout ones.
I love the concept of badges that active hosts can acquire at special events apart from the badges they will instantly earn by being hosts, badges for local, district, etc. events. --- if you are a scout or Royal Ranger you know what I am talking about.
At least at Nats, hosts will be required to all wear their uniform together on an assigned day.
I prefer long-sleeved. Then we can just all agree what pants type and color to wear.
Now....THINKTANK PLEASE.
