Revelers wandered foolishly about in shirt sleeves despite nose nipping temperatures. Even the rice-crispy sound (thanks for the phrase, neighbor, Babs!) of rattling trees added to the festive mood. Steam rising off melting tarmac added a sense of mystery.
Everything about the day seemed to cry, "shake it, Baby, shake it."
In days gone by, Mardi Gras/Fat Tuesday, was the day when everyone scraped together the last bits of fat and feasted as best they could before the long final fast that awaited early crops and hunting. After the feast, as reality set in, people would go to church to be "shriven" of their sins, to confess and cleanse their souls. Today, I went to the store to stock up before rain sets in again. Instead of going to confession to cleanse my soul, I'll brush my teeth before I go to bed. Its quite a reversal of fortune from what my scandinavian ancestors knew.
Two of the practices lost in Protestantism's hey day are confession and fasting. If you don't have to, why put yourself through it? Party on!

Will it really all go away if we just ignore it? Or might we accept the moments of clarity offered by a Lenten Fast, setting aside non-essentials while what is vital emerges: our fears, our addictions, our hubris, all the accrued debris in our souls that Jesus offeres to sweep out and replace with space for grace.
