There are tons of bikes out their that can do both reasonably well. If you want to do a 70 mile road ride, you'll probably want something without a suspension fork and with a lower position than a typical hybrid allows. My recommendations in no particular order:

Trek FX series
Specialized Sirrus
Kona Dew
Jamis Coda Sport
Schwiin Supersport
K2 Astral
KHS Flite 200
Marin Muirwoods

There are plenty others too. For dual use, look for a bike with touring gearing, either a 48/38/28 crankset with a wide range cassette (at least 12-25, an 11-30 would be better suited for steeper, offroad climbs though) or a road crankset (52/42/30) with a MTB cassette (at least 11-30, more like 11-34 if you plan to do some decent offroading). The problem with a MTB on the road is you run out of gearing on any decent downhill and you probably won't ever use the inner ring on the crank. Touring gearing will allow you to pedal on most downhills yet still give you low enough gears to get up steep offroad climbs.

A lightly treaded tire (like most of the bikes listed come with) will be good for both on and off road. For a 70 mile ride, I'd swap in a pair of slicks though. For more serious off roading, something a little more knobby would be better too. It's really tough to do it all with one bike but with 2-3 sets of tires you can come close.

You are right.I dunno I guess I need to look around some more.I have developed a pretty good relationship with my LBS and feel I should buy from them.but if they really don't have what I am looking for (whatever that is)I should move along.we will see.
I did get a roadie given to me.it is old but seems solid enouph.needs some work though.no biggie
thanks for your time and opinion I will think some more on it

Welcome to the world of cyclocross. Looks like a road bike with knobbies. Cannondale's example. (http://www.cannondale.com/bikes/06/CUSA/model-6XR8.html)

The Jamis Coda Sport is basically a cyclocross bike but without the drop bars and with slightly different gearing (road crank with a MTB cassette). It also doesn't cost all that much compared to most cyclocross rigs out there. With that said, I'd love to add a cyclocross bike to my garage.

As long as you are not looking to ride single track MTB trail and you are talking about rail trails. I think you will be happiest with a roadie withroom for larger tires or cyclocross. That way you can put smaller tire on when you want to do mostly road riding.

Get a cyclocross bike and two sets of wheels - one for road riding, one for off-road.
