The Kids Love to go Biking with Dad & Mom.  They ride in a kids trailer that Gene pulls behind his bike.  We take them on an incredibly nice Bike Trail called the West Orange Trail.   Here's a little info about the trail:  

The West Orange Trail, is the Orlando area's longest paved trail.
The minimum width is at least 6 feet, and the current total length
is 19 miles. With the close proximity to Orlando, it is also heavily
used, with over 55,000 people a month. The western end is located
2 miles west of Oakland, at the county line station where bike and
blade rental is available. The northeastern end is located in Apopka.
This is also the end where the trail will be extended north an additional
11 miles in the near future. The majority of the trail runs along Lake
Apopka, so it is quite scenic. 

Here are some website about the trail:
