Why is it pedestrians who would never blatantly step right off the curb into the path of an oncoming car think it's ok to step in front of a road bike traveling at over 20mph?

I took a lazy ride in the sun along the beach today. A few miles of very, very slow (5 - 10 mph) yet adrenaline filled "dodge the pedestrians" (reminded why I never ride this part of the world on gorgeous beach days or weekends) followed by several miles of glorious flat out riding w/ the ocean on my right and the wind at my back. Total miles only 15 w/ an avg spd of 15mph but was out for the fun of it today after riding hard daily all week in rain and cold and generally :P weather.

Don't forget to have fun out there Ladies

Headed up to Maine now for a few days - debating on bringing the bike. Have done so in the past but... only going Sun to Fri sooooo.. should I bother?
