Village of Linden also has a Next Door Group, that would be very informative for finding out about your neighborhood for those who actually live there.

As Bogie mentioned, your salesman if showing homes in that Village, should of showed you the amenities for that area.
You'll find 95% of the posters on this message board live in the established Villages, so were really not familiar with the new area, plus that area is growing so quickly new paths and bridges are always opening up.
A quick glance at the map shows Linden as being on the southside of the Turnpike, so as far as golf cart travel you'll be limited to staying on that side of the Turnpike until one of the two bridges under construction across the Florida Turnpike is opened. If you don't have a salesman, I would suggest getting one, go to the sales office at Brownwood. Also they will be able to give you a map, and the new areas to a certain extent should be included.
