Thanks for all of your responses. I'll update you when I select a race and let me know how everything goes.
As I went back to read my post and the responses, I was a bit embarrassed because it's just water, right? I should be able to do that. However, I have seen, heard and even read (on other not-so-nice forums) how some runners get very upset because the water wasn't help in the right way for them. They were really upset because they had to stop and walk through the station or something of that sort.
If I happen to meet any of those people while I am volunteering, I'll do my best not to let it get me down.
Thanks once again.
