I'd recommend the Horse Shoe Curve for sure. Donner Pass was a disappointment as Rich_S said for all those reasons.
I have too many new free routes I can't remember all of them, really great stuff from right here at RWA's library. Fraiser and Cariboo, while being a payware route, is such a fantastic third person route, it's just great! Johnathan did such a great job! Just so much new talent in the last year, it's amazing what these folks do.
