Relive the pretty dress ride, or tuck that shirt in, shine those shoes, and put on your seersucker, fine lads! Let's dress to impress on this day.
Dress in real or fake plants and flowers. Heavily floral-patterned outfits work, too.
Appreciation of Greenery
Bike around and appreciate people's yard art, gardens, and unusual small things... Yell out "nice yard!" to those you appreciate.
How, how about you get out and appreciate YOUR yard? Dust off the lawn games, and prepare for an afternoon tea party and some badminton.
New (to You) Parks + Greenspaces
Explore! Pull up an online map of an area of interest and find green areas that are new to you -- parks you've never seen, school playgrounds you've forgotten, a tiny cemetery, a swing set in a parking strip? Construct a ride where you connect a handful of them (How big a hand? How full? You decide!); take pictures of your bike / yourself / your ride buddies along the way.
Stop and Smell the Roses
Head to the nearest garden and stop along the way to appreciate the most fragrant flowers you pass.
