Marco Rol's Jersey show that same weekend (March 3-4, two days only) should be a much bigger deal for collectors and dealers since the Hunt show was cancelled. Marco's Oaks show (April) has the best dealers, especially cards, of any show outside of the National, it just needs collectors to show up. And I would certainly deem His Chantilly show (March) worth going to if you're within a couple hours drive. And for autographs of current players, his lineups are also the best anywhere other than the National. Here's the link to the website for his company, Collector's Showcase of America:

Hunt's Philly show, although diminished from the old days, still has many good dealers and you'll see some first-rate stuff there. I guess their schedule has been thrown up in the air, but hopefully they will have a spring show somewhere.
I'm sure there are many other good shows around the country that are worthy of mention.
