It will be a little longer by the time I get from my house to where you start. I am off Circle Drive on the other side of 71. I am driving to town today to pick up a bike at the shop and ride to Frankenbike. I will print out the directions and see what I think! As a general rule, i am not against hills and, in fact, sometimes seek them out. Looks to me like I would want to allow more time than my current ride. I might leave the house super early to avoid traffic and just use the ride to go in and take my easier ride home.
