hey c e,
we have the bob revolution, duallie and absolutely love it. i couldn't function without it!! i have a 2.5 year old and an almost 1 year old and it has been great. we actually went to the mountains and did a 5 mile hike/run with the boys this week while on vacation and it was amazing on a single track trail over a ridge at deep creek near bryson city. it is a little pricey, but you can buy it at rei in atlanta and if you are members you can wait for a 20% off coupon to buy it and it really helps a lot. the canopy shades everything on the boys except fromt he middle of their shins down and it adjusts to allow more sun if you want. it does have a swivel/lock front wheel. i do all my grocery shopping with it, pushing it with one hand and pulling the cart with the other. feel free to e-mail me back if you have any other questions. we really do recommend it--we also have the single bob revolution, which we got when we just had one little one. my husband and i were talking this weekend about future hikes where we may have to bring both strollers as our family grows. good luck
J.
