ROXBURY, NJ – Believers in The Law of Attraction might frown upon Allison Kohler’s plan to wear waterproof boots Saturday morning. If the Succasunna resident and promoter of the Just Jersey Food Truck & Music Festival would just have faith it’s not going to rain, then “The Universe” would be forced to comply, they’d argue.

Indeed, they would insist, Kohler’s desire for sunny skies over the Waterloo Village concert field would be better served if she just went ahead and wore the same sneakers that got thoroughly soaked June 27, when the first festival got hammered with precipitation.

The “thoughts are things” folks would also tell Kohler to stop watching weather forecasts, but it’s unlikely Kohler would listen; She can’t help but worry, given that the first event was a washout. “I’ve been tracking the weather on my computer,” she said. “Nothing I’ve read has it like it was last time. A couple of the sites I’m tracking have it more like light rain from 6 a.m. to 10 a.m.”

If that’s the way it works out, Kohler won’t be the only one pleased. The three festivals (another is planned for Oct. 3) are not only money-makers for Kohler’s JMK Events, they also benefit the Roxbury Food Pantry. Visitors are asked to bring a can of food or a boxed, non-perishable food item to be donated to the Pantry.

For Saturday’s event, Kohler has booked 31 food trucks, several food and alcohol purveyors who don’t have trucks and some popular bands. There will be craft beer, sangria and other vendors too.

“Obviously our first event was rained on from start to finish,” said Kohler. “We ended up closing almost four hours early. There was not a large attendance … It was a very long, disappointing day for all involved.”

If Kohler’s meteorological assessment holds steady, the rain will be light and ending just about the time gates open for this Saturday’s event. Right about then, SPINN, a female trio from Morris County that performs “city-country” music, will take the stage.

At 11 a.m., the veteran country rock cover band Kinderhook will perform. That’s a name likely to elicit a “They’re still around?” response from anybody who experienced the late 1970s and early 1980s New Jersey rock club scene, including late nights at The Final Exam in Randolph. (Yes, purists; Kinderhook used to be Kinderhook Creek).

When Kinderhook is finished blasting The Outlaws, Pure Prairie League and the like, the stage will be occupied by another popular Garden State cover band (whose members wear the types of Buddy Holley glasses that prompted many of us to try contact lenses): The Nerds.

After The Nerds wrap up a 21/2-hour performance, “Baltimore’s rough and ready Thin Lizzy Tribute” band, Black Rose, will rock the food trucks with Jailbreak, The Boys are Back in Town and other gems by Phil Lynott and his fellow Irishmen.

“We have some great local entertainment,” said Kohler, noting Black Rose is the Baltimore Ravens’ halftime band. “We tried to hit all the genres here.”

It will cost $5 for adults to get in, but that price is reduced to $4 for those who bring food for the Food Pantry. Kids under 12 are free. The Waterloo Concert Field is at 1053 Waterloo Road, just past Waterloo Village, in Allamuchy Township.
