I used to live in Florida..I have the impression California citrus is less acidic? As to smoke days Denver...Maybe last year we had 3 of them..Does not change my number of non-riding days that much...Some years we have no smoke days..This is Not LA..
Your mom is probably more inland, maybe more vunerable to fire in the backcountry.. Maybe bad luck with the fires could change my numbers, but most years I will stick with my 340 days.
I hate heat and had enough of the cold. That is what effects me..
I think my numbers are pretty accurate..Most cyclists I ride with would agree...Only problem here that fazes me, overcrowding..
