The E Harrison to Lillooet is one of my favourite rides. Most has been covered in this thread, but I have just a small caution to add

OGS!! Last time I went through, there was a pack of semi ferall dogs that almost brought me down. Last km or so before the Lytton ferry, just at the end of a sunken lane with apple trees on both sides. Watch out.HORSES!! About a 1/3 way between Lytton ferry and Lillooet, there is usually a herd, some will stand their ground and kick if you pass too close.Ride safeMike
