You gotta decide where you want to cross the Bush. Some riders recomend Ohio, but I found the limited sight distances along that four lane, shoulderless, fairly high speed street to be less than ideal. The cross at Independence/Waterview is OK, but you have to ride those big thoroughfares for quite a ways to use that crossing.

My decission has been that Custer is the best of a bad lot. You don't have to ride it very far north, and south of the Bush it's actually pretty calm. It's straight and wide as well.

Based on riding Plano and Richardson for the last 30 years, I'd probably go (southbound): Quincy-Home-Old Pond-Archgate-Southgate-Preston Meadow-Denham-Builtmore-Sailmaker-Mission Ridge-Landershire-Round Rock-Maple Leaf-Stratford-Mollimar/Cloister-Wilson/Westlake-Custer-Westwood-Weatherred/Goldmark-Midpark.

If you don't want to run the signal headed northbound on Stratford at Park, take a book to read while you wait for a green light.
