I went indoor skydiving last year at Niagara falls, I had already booked my first AFF skydive so just wanted to get the experience. Its really fun, although doesn't seem to last very long when your in there, and if your good the instructor will let go and let you try spinning.
Went to go do my first jump at Grand Bend near the end of June but the clouds were too low for the whole week! So now I'm heading back in a couple weeks to do two jumps, hopefully the weather cooperates this time
I'm hoping to finish all the jumps required to get my skydiving ticket by next year! (Fingers crossed!)
