Also keeping in mind (and not singling anyone out... I'm definitely this way) some of us are CHEAP
I usually get my helmets from someplace online. I like my Bell helmets so I usually just google them and "remember" the online retailers:
Safe Racer
IO Port
Racer Wholesale
Summit Racing
There should be some local places to you that will likely be way more expensive than the internet but at least you can go in and size up your noggin. And different helmets fit differently too. Like a Bell XL might fit differently than a different company.
Not sure if anyone has hookups... maybe check in the motorsports section? And if there's nothing there, maybe ask... some of those guys might not be checking out this convention section.
When I get more info, I'll be able to pass it along as well as to explain anything additional, if necessary to make it crystal clear.
Thanks... we'll be on the lookout for your letter
I have full confidence that the event will fill up. I'm hearing from people on forums I didn't even know existed! And I'm not even really marketing this thing yet!
