Before staying in Central City, Colorado, I'd never heard the term 'leaf peeper.'
According to Grok.com:
"A leaf peeper is a tourist who travels to view and photograph the vibrant fall foliage, especially in regions like New England.
The term is lighthearted but sometimes carries a mildly mocking tone from locals, who may see these visitors as clogging roads and trails during peak "leaf-peeping season" (typically mid-September to late October). It's a popular activity, with designated scenic drives, festivals, and even apps tracking foliage changes."
The staff and regulars at the Denver West/Central City KOA mildly mocked said leaf peepers.
HOWEVER, as we guided Rigsby through the Blue Ridge mountains, I understood the allure. Fall colors are amazing! I neglected to take photos, so I grabbed this one from Pinterest.
