we've been eating, or rather sucking down a seedless watermelon just about every week this summer since they've shown up in the markets this year.
i've heard that this year has been a bumper crop of high quality melons in the u.s. because of the weather. as far as i'm concerned, it's true. i can't remember enjoying eating watermelon this much as sweet as it's been, but also for teaching my boy to spit seeds.
i bought a seeded one just for that reason.
otherwise, the seedless are fantastic, imo.
here's some info from a local green grocer/tv guy: http://www.producepete.com/shows/see...termelons.html
