I grew up in the Monticello community . There are actually three lakes each separated by a darn , Monticello , Bob Sandlin and Cypress Springs.
Alot of people in the DFW area have summer homes here which helps my A/C business some in the summer! The Autumn Trails event is a Parade , car show and a small swap meet which is more like a smal flea market. The parade starts at 10:30 but is best to get there early. The parade ends up stopping downtown where they close the street and have a show , where you will see the most Model A 's that I have ever seen along with Thunderbirds ,55-57 Chevys, a few AD'S, musclecars and so much more. The folks have a good time throwing candy to the kids and honking their Ooga horns as they go along the parade route. Hope to see you there , bring the family and have a great time!
