“Hey, Susie, wanna go to LoDo with grammy and do some shots of Jager?”

Spring is strange. The weather is unpredictable, but leans toward unpleasantness. In winter, the weather is predictably bad. Once spring hits, there’s no way to find a groove. Bar patios are open one minute, closed the next. Irish coffee is the drink of choice on Friday night, but Saturday sunshine has everyone craving chilled white wine. An insane snowstorm one night has the city preparing to spend the weekend at home under blankets; by Friday, temperatures are in the 60s.

Clothing choices are all over the place, of course. How fortunate we are, then, to have the Snuggie, The Blanket With Sleeves. It’s a fine garment for spring, with long-sleeved warmth in the front and an adjustable opening at the back for ventilation. And it is certainly as weird-looking as spring weather patterns.

If spring is Snuggie season, now is the perfect time for the second annual Snuggie Pub Crawl. An intrepid group of Snuggie enthusiasts are once again hitting LoDo, fully prepared to be mocked in their monklike robes.

It’s a pretty sweet deal: For a $30 registration fee, Snuggie lovers can traipse around LoDo with a horde of like-minded new friends, drink beer and participate in classic drinking games. There’s a Snuggie-decorating contest, too, with prizes for the most outrageously customized Snuggies.

It’s going to get hilariously messy. Think of all those long sleeves, attached to flailing arms, dragging through spilled drinks. The laughter from onlookers probably won’t bother the Snuggie set too much, though, since the pub crawl registration fees benefit the MS Society and Big Brothers Big Sisters of Colorado.

Learn more about the Saturday crawl, which starts at 3 p.m., and how to register in advance for $25 at yelp.com/events/denver. There are a limited number of spots for $30 at-the-door registration, too.

– Title-free. March Madness is taking over –

The college basketball tournament is likely to be on almost every bar TV in town during the next week and a half. There will be no avoiding it, except at the rare watering hole that lacks a TV. My Brother’s Bar (2376 15th St., anyone?)

For those that need to take a timeout from hoops overload, the Denver Art Museum (100 W. 14th Avenue Parkway) hosts another installment of its “Untitled” series on Friday.

The theme is “Rogue,” and features artist discussions, guerrilla yoga breaks and fun “art-personality” quizzes. The Postman will DJ, and the Hideous Men and Natural and the Disasters will rock live music. Buntport Theater occupies the third-floor freight elevator to perform another episode of “The Joan and Charlie Show.”

Of course, there will be drinks, too. It’s Friday night, after all. “Rogue” is free with museum admission: $10 for Colorado residents or $13 for nonresidents, with discounts for students and seniors. The party starts at 6 p.m..

– Get up! –

The festivities start tonight for the 10th annual Caffeine Music and Arts Festival. The Church (1160 Lincoln St.) hosts a Caffeine pre-party with DJ Jon Bishop, who also spins Saturday night at the main event.

Then, Caffeine lights up the 1stBank Center (11450 Broomfield Lane, Broomfield) on Saturday, keeping dance-music fans up all night. This year’s lineup features five stages of music, including sets from DJ Micro, Richard Vission, John Debo, Dave Audé and more than 50 others.

It’s an age-16-and-up event, with ID required to drink. At press time, tickets were $53 — prices will be higher at the door. Visit caffeinefestival.com for the full lineup and to purchase tickets. Doors open at 8 p.m.
