Carleton in the Springtime

Campuses are usually most interesting and exciting in the fall, when a new academic year starts, but springtime isn't too bad. Herewith, a few recent sights that make it fun to walk around the quad:
1. A giant white tipi right in front of the 1890s observatory.
2. A half-dozen frisbees in mid-flight at any one time on the Bald Spot, with ten times that many students lolling on the grass, "studying."
3. Signs warning that the lawns have been treated with gluten. What? Gluten?
4. Students wearing flip-flops, shorts, and t-shirts no matter what, dammit, even if yesterday's balmy weather is in Illinois now and it's 40 degrees and windier than the first ten minutes of The Wizard of Oz.
5. Classes meeting outside all the time, whether at a dewy 8:30 a.m. or a humid 4:00 p.m.
6. Leaving a meeting and walking straight into a crowd of undergrads doing tai chi under the direction of Prof. Qiguang Zhao.
7. Faculty who wear crazy hats that make them look like Andean peasants, Australian ranchers, or Jack Abramoff.
8. Several gay couples - male and female - holding hands as they go to the student center. I don't know if it was "gay holding hands day" or what, but it's heartening to see.
9. Tangled mobs of bikes at every rack on campus.
10. The campus tabby cat, sleeping among the early-blooming flowers in the bed outside my window.
