Yep, I fly balloons however I've taken this year off as I'm busy getting a divorce. Any single female pilots out there ?.... oops, wrong thread.
The BBAC should be able to put you right as will Cameron's in Bristol. Check out their websites and if you call Cameron's, ask for the lovely Hannah as she will know the details of your local club.
If you haven't developed a propane habit, you will be blown away with your first flight if the pilot does some "tree skimming" over a forest or does a "splash and dash" in a lake. My best memory is having breakfast at FL105 over Hungerford (just legal) looking at the Isle of Wight. Crossing the Severn was pretty awesome too. Discovering that RAF Wellford isn't just a "disused airfield for navigation purposes only" on day 2 of the Gulf war was rather fun.
Enjoy !
