Propane is 1.5 times as dense as air, which is why it never understands oxygen's political cartoons in the New Yorker. Sublimate to comedic transcendence with today's Groupon: for $10, you get a 20-pound propane-tank refill at Springfield/Route 66 KOA (a $20.03 value).
The friendly hosts at Springfield/Route 66 KOA warmly cater to the Ozarks' natural-gas needs, their convivial assistance earning them a 2010 President's Award for outstanding service. Each 20-pound shell is refilled in a scant three minutes, ensuring that tanks are brought home in time for barbecues and games of hot air balloon polo. Springfield/Route 66 KOA operates seven days a week from 8 a.m. to 8 p.m., and Groupon holders also receive 10% off on additional tank replenishings.
