Never been to Timber Ridge, but the general consensus among people I know that have tend to like Bittersweet better. I think Bittersweet may be a bit pricier though, but it's a fun place to ride. If you stay off the blacks I think you can buy a cheaper ticket that accesses a lot of green and blue terrain, however. Went there for the first time this season and had a lot of fun. Heading back there this Sunday likely.
Their beginner area is a really great place to help a new rider in his/her transition to blues, and their runs are surprisingly long for a southern Michigan hill.
That sounds a lot like what I am looking for. I have started blues lately, but my last trip out was a bust - it was this past weekend and I forgot about the holiday. The hill was packed. I am assuming that weekdays should be pretty clear?
