You all did good for the first time. Looks like everyone got up. Next time you go, remember that if you want to stay between the wakes, pull harder on the handle with your leading hand. Beginners tend to pull on the handle equally with both hands, which makes them butter slide--causing them to go sideways outside the wake.
Wakeboarding and wake surfing are great fun. Ordered a new wake surfboard yesterday. It's a skim board which should be fun for those (my nephew) who like to do tricks. A couple more weeks before we're on the water.
