there may be snow on the ground, but i've got dreams of next summer's rides in the head!
one source of ideas for rides in the US that i came across thru SVrider.com is a publication of the US dept of transportation called "america's byways". this is a really nicely produced 124 pg booklet with 1/2 page descriptions (incl a few words, a map, and a postage-stamp-sized photo) of close to a couple hundred 'scenic byways' all across the USA. mostly the orientation is towards 4-wheeled travellers, but a lot of the roads would be very interesting riding too.
check out the website:
you can order the free booklet online - i got mine in about 2 weeks.
there are lots of online photos on the website too.
