I don't really drink - girl wants to meet for "drinks" what to do? NEED ADVICE!!!!

Alright so a friend of mine talked me in to trying the "online dating" thing. Long story short I have been talking to this gearhead girl. We agreed to meet at one of the local car cruises Saturday night.

So she sends me a text today and asks what time I want to meet there. I said that I am meeting my Brothers and going to Monster Mopar Weekend Friday and Saturday that I was planning on getting there around 6:00.

She said that they (her and her family) were going out on the river (yes she is a country girl) and won't get out until about 5:00. So she wanted to know if I could meet up later for drinks?

I am not big on drinking, I may have one or two brewskis with food but... I don't get drunk. Sorry, just not my style.

What do you guys think I should do?
