Have you guys even had a freeze?

Yes ... several. The coldest was in early Dec, about -6ºC (21ºF) one night. Since then no frost until just recently with the cloudless skies, and by morning a light frost had formed at +1ºC (34ºF). We're now overcast this morning and 6ºC (43ºF).

As far as visitors noticing palm trees, I doubt it. Most people rarely notice such things unless they happen to be avid gardeners. They where more likely to notice the mild weather.
