DUB,

Hmmmm! Around 0 deg - a little chilly for x-country skiing, but doable. 10 to 15 deg - gettin better. 20 deg - perfect. 25 and above - starting to get uncomfortable. 30 and above - put away skis for next year, turn on air conditioner, break out suntan lotion, get on roof and catch some rays. Oh yeah, pack up ice fishing shanty before it ends up on the bottom of the lake! Early summer has arrived! LOL!!! YMMV

Best regards, Dave S.
