Has anybody else seen these awesome goggles brought out this week from Recon Instruments? They have GPS and a LCD display inside which shows your speed, altitude, vert, time, temp, long/lat...in real-time. You can also download all the data at the end of the day onto your PC and watch play-backs overlayed on a Google image.
