I heard the Covered Bridge ride is a do-not-miss. I'm gonna sign up for it this year.
Another place to check is the LBC, Lancaster Bicycle Club. http://www.lancasterbikeclub.org They have a section on the left side of the homepage called Scenic Tours of Lancaster County. They make available descriptions and cue sheets for many wonderful tours that you can do on your own. Very accurate regarding difficulty and sites along the way. I can recommend the "Short Ride to Intercourse", "Strasburg RR Stoker", "Dutch Delight" or "Kitchen Kettle Klimber". They also have a "Covered Bridge Metric Century" cue sheet in there. I have done parts of this and it's very scenic. (still not up to the whole thing yet - I'm a newbie)
The "Mount Joy Jaunt" is good b/c it takes you to Bube's Brewery - even if you don't ride there, I highly suggest you go there for dinner. They have a couple of restaurants with different themes/atmospheres. The Catacombs at Bube's should not be missed. If you only go once, go to this one. There are caves underground used for brewing the beer way back when. Very cool. They do a whole presentation and tell you the history of Mr. Bube. (pronounced Booby- I can say it with a straight face now but it took me a long time to do it. ) Try the Seafood Mornay. DEEE-lish. The martinis are wonderful. One is enough to put me in a very fun mood. (Actually, they give you a small carafe along with it, so you get two really... "tee martooni's please!" ) They have Feasts on most w/e's if you are up for an adventure. I can't do them justice so you'll just have to look that one up. You need reservations but it's worth the trip. http://www.bubesbrewery.com

Hope to see you at the Covered Bridge Ride. Maybe we need to have a TE meeting place at this one too? I probably can't keep up with any of you yet, but it would be my privilege to meet ya.

Good luck. If I hear of any more rides of interest for you, I'll post again.
