yes there are signs out there to predict the future not 100 percent but i would think 50 percent maybe . example i work at a pizza place for 6 years now i can tell when its going to be busy and i can also predict when they should call but it doesn't always happen. last sunday ago it got busy at lunch time then it ended at 2:30 how did i know well simple i know there was going to be a football game that sunday and when it turned 2:45 pm the phone rang i picked it up and said hi boss he sid hw did you know it was me i told him i got that gut feeling. and here is another example i live in phx az we bought a new house for 100,000 then the houses went for three times that value they told us there should be a Wendy's and office max right next to each other and a hark-ins some where in the same plaza but they stop building houses when the houses went for tripled in price then the house industry took a turn for the worst three to four years has past and they are building a hark-ins across from the circle kay so that proves you can predict the future there are sign to fallow and my dad says every ten years the home industry's almost crash i been around for 20 years now and saw the same thing twice. here is a clue for when to buy and sell houses when u see more than one crane in construction then its time to buy.
