Hi Jon
Shoveling snow huh! That's gotta be tough on the PN - can't quite relate as I don't get snow here - even in winter (it's summer right now in NZ) but the heat is worse for me.
Today I mowed a patch of lawn (about 1/8th the size of my whole yard). This patch is a new area sown in spring, and with lots of TLC, it's slowly catching up to the rest. The lawn guys are due tomorrow but I don't want them going over it with their ride-on mower yet. Just that 30 mins of effort (in 80 deg. F) was enough to fire up the PN.
Hope you get some recovery time before the next snow is due.
May the Force be with you - that Jedi bathrobe may just have some mystical power.
