I'm pretty sure I'm going to Americade. I'll let you know. I also go to Laconia. My brother has a house on Lake Winnepasaukee which is only 3 miles from Weir's Beach. About a 6 hour ride (200 miles mostly on rt. 4 all the way). 45 mph. I must pass 1,000 cars along the way. It's good to have a Buell XB.
For your trip.....bug repellent and sunscreen. Also bring something to put under the kickstand. Found mine laying in the mud one morning after a rainstorm. Once that long kick stand goes deep in mud you ain't gettin it up by yourself. Might be fine before going to tent but if it rains, down she goes. I also found a very tiny packed bike half cover called "Not just a Bike". Forget manufacturer. Also medical kit. Don't hesitate to use 5 hour energy if you get a little tired. I actually dozed off once on an extremely hot day on a long trip. Yea, dozed off! On a bike! Shezus. I like the UP Michigan, Canada idea. I've been in UP and on southern side the beaches are magnificent. Iowa, Illinois, Indiana, Ohio are completely, and I mean completely FLAT with very little else. Beautiful in their own way but your route is far superior. Also, you WILL freeze going over the passes in Colorado or anywhere in the Rockies. I was there in July and it was 45-50 in passes over 10,000 feet. In May it's possible for anything, even snow. Check out weather before attempting a mountain pass.
