From The Geography Collective who brought you Mission:Explore, there is now a campaign called Love Outdoor Play. Their mission statement is:
"Having the freedom to play outdoors improves the well-being of children and their communities.
Together, we are building a visible community to support reasonably safe exploration, adventure and play.
Wherever you see a Love Outdoor Play sticker or symbol, you’ll find people who welcome play and are looking out for young people."
Woo Hoo. If you're in the UK, get your sticker today and join in.
