I'm sad to hear about your dad. Take your time. I don't think grief can be rushed. When you're ready, the bike will still be there. Winter can be so bleak, anyway. Spring is a time of renewal, and maybe you'll wake up one morning when the sun's out, new life is emerging everywhere, and find you can't wait to get up on your bike. Until then, or whenever that happens, hang in there, Ratchet.
