      I think showers seem to be surfacing more in consciousness because of the Leonids. It's been observed that every 33 years or so, they pick up in activity. This because the Earth passes through/near the parent comet's orbit soon after the comet passes near Earth's orbit, so there's probably a higher density of ice and rock chunks. The activity was supposed to peak in '99 - '00 as it did in '66.

    Pictures are here and here for 2002.

    Even this year's show, which got up to 600/hour at the peak,and thus the 2nd best show in my experience, was a letdown.

    We won't see that again from the Leonids for about 97 years, if we see it then. It is possible another surprise show could come now that they are getting better at predicting, but I doubt it.
