Sounds like an interesting ride! And not too far from my riding area. At least for some of it. The area around Palisades Park is lovely! I've bike in that area on TOMRV.
As for sleeping bags, that's always a tough one. You don't want to take more than you need, but you don't want to chance freezing at night! And it can still get pretty chilly at that time of year around here. I think you'll be ok with a 20 degree bag. You can always unzip and let air in, if you need to cool off. You can take a small sheet or light fleece cover and lay on top of the bag if it's really warm. I guess I've always had more problems the other way - keeping warm enough, so I tend towards making sure I'll stay warm. Besides, if you are taking your extracycle, and I'm assuming you are, since you're taking the blender
, you'll have room for a slightly larger sleeping bag. V's idea is also good. A light bag plus a liner. 'Cause then you've got a light bag for the really warm nights of summer. Decision, decisions........ never easy.
