You'll see several doing the single space after and before those sharing the line. No biggie there at all!
Odds are you will not be the only first timer there (if you go), so no biggie there at all!
If you meet up with a group early, you can pick out those who'll be of real help (actually, they'll offer), well before you line up. You'll soon find out that their help in becoming more comfortable with the whole thing is the greatest boost, so no biggie there at all!
As a vet who still has some dark minutes here and there I can tell you with certainty that taking part in anything to show appreciation for what our men and women do will ALWAYS be a good thing. No matter how "well or badly" anything goes, being a part of some tiny form of "thanks" is worth more than every dollar most of us ever earned in service. . . . . . . SO.... no matter what you decide, thanks for the consideration of not wanting to take away. Lose that fear all together, but thank you.
Lastly, it's all up to you. If you're comfortable trying to meet up with some other riders who'll be in the lineup, go for it and let them help ya along. If there's no one what so ever and you're comfortable finding good folk to talk with and pick up some comfort points, go early and find some good people.
If not, then there's always another day and somehow there'll be a way.
Either way you go, keep the rubber down and enjoy the ride!
PS: some quick points if you do decide to go. No matter your usual routine, do at least this...
1)Verify tire pressure and fluid levels (don't forget brake fluid) prior to the lineup.
2)Get there with a full tank of fuel even if you're only going to use 1/4 gallon.
3)Verify all lights operating properly as well as horn.
4)If you have allergy, headache or other such issues even remotely common, take needed medication with you or actually use precautionary medication before you go.
5)I personally suggest at least a small hand towel and some water.
