A Sparrow glide park would be kind of cool. We already have bounties for killing things, why not bounties to upgrade our sparrows? I would really like more of an excuse for using the thing than simply because "I have to travel from point A to point Z". They are a cool concept and I think they should be a little more than just a thing you have to ride. Plus, there could be a back story like the crucible. Crucible makes better fighters of guardians. Sparrow park, or whatever it would be called, could be used for making better recon scouts and also as a way for citizens to relax and try and stress less about the darkness on the horizon. The vendor could be a hunter vanguard who has default stock mods for your sparrow that can be paid for in glimmer while points would be earned in races or stunt tracks and can be redeemed later on for ranked items. Edit: There would have to be sparrow class races though. And time trials for solo races. Example: complete 10 sparrow flips in X minutes. Just an idea, would be cool if that could be applied to ships too but one step at a time.
