Anyway, between walking 2 miles (dragging a cart full of supplies) down and walking 2 miles back (with same cart, only slightly lighter) for the fireworks, and today's mile up, 2 hours of standing around, and a mile back, I was wiped out ... totally "losing gas" about 3 blocks from home. I did make it back, but ended up crashing for nearly 5 hours.
Sure, I'm usually rather sleep deprived and could use the shut-eye ... but it really bugs me when my body takes control of the scheduling! Now I'm WAY behind on all the projects I'd hoped to get done today. Bleh.
