My step mom e-mailed me this table from the Unofficial Guide. Here is the rest of April. The gridlines won't cut and past in, but it is the date, then the estimated crowd on a scale of 1-10, the best bet parks, then park to avoid.

So they don't think crowds will be too bad at all. I am so psyched!

I didn't have much luck trying to format the table. If anyone wants me to e-mail the whole thing (I goes throught 12/31 send me a pm with your e-mail.) If I knew where she got it I would post the address.
