Monster Jam in Seattle week before SX

I just recently saw that there is a Monster Jam event the weekend before supercross in Seattle and it made me curious about how that could effect the conditions. Do you think it will be better, worse or indifferent for the soil conditions, as we all know it will be getting wet throughout that week but being that Dirt Wurx will already have a jump start with dirt being on the floor, will that give the soil more time to dry out if they tarp early enough or will it even matter??? I’m a little bummed they are actually moving the Seattle race up instead of back as the weather already isn’t great in April and now we’re in mid-late March.
