I suspect that March and April are the two most difficult months to plan around of the whole year. Other months are well known for their somewhat predictable weather but these two culprits must interrupt more projects than any of the others.
Along with sending me indoors (away from much needed outdoor preparations) I also find myself changing my wardrobe on nearly a weekly basis. I think older people just give in and wear those "old people sweaters" mainly to avoid the winter to spring and back again clothes changes (we may be old but we've learned something along the way).
Most annoying, however, is not knowing how much time we have for an outdoor project before it's interrupted again, and I'm forced back to that indoors project I was drawn away form when the nice weather came in the first place. I guess this is why farmers (in an attempt to guide the Almighty, and the poor farmer) started their Farmer's Almanac.
None the less, reguardless of any devices known to mankind, we are (and will continue to be) caught up in this drama (and dilemma) that has romantically been nicknamed "Spring Time in the Rockies".
That's my opinion and you're entitled to it.
