^ Ride fast, use a stiffer board that doesn't flex and pop with every inconsistency. You want to smash and carve through the small bumps, not feel them. I went to Jiminy yesterday where it hit 65. Did more surfing than boarding and it was hella fun. Especially the waterslide.
Remember to lean way back when you hit puddles and pools, they create a lot of drag that slows you down like someone tied a bungee cord to your board. You want to hit them fast enough to make it through, but you don't want to go cartwheeling either.
I've been there a few times. One night it was crazy foggy and right about where you took the pic there were not any lights - it was cool riding and not being able to see anything. What I hate is that you can't just get off the lift and start your run - you have to skate while you pick which run to take.
I like riding in Spring slush. Again if you hit some really wet parts your board will instantly slow down.
Also it tends to get pretty bumpy towards the middle of the day - but it is great to ride and not even need a jacket or gloves.
