We have noticed the same smell on the walk to the MK from BLT. I think it is a drain.
Interesting find!! Indeed - this site notes the Boxwood smells like Cat Urine and i do recall seeing some plants that did indeed look like boxwood nearby, but i wont be back soon to check.From Contemporary to MK there is the foul smelling BOXWOOD (BUXUS SEMPERVIRENS)
Just to throw a wiggle in, i didn't notice the smell when i walked right in front of the Alps booth though - only when i was on the other side of the walkway.To sum up and end the thread:
Current smell is cheese from The Alps food and wine booth
Previous smell is poop from the crappy sewage system, and yes this is the same smell as over at Innovations.
