Yeeehawwwww!!!!
I'm excited for you, GingerK ... but can't give you any advice on LAs.
Gather info so you can be more knowledgeable. Then head off on that road trip!
Go with the mindset that you are still gathering info and NOT making a purchase right there and then, that day. Surely, that would be of no surprise to the store. I'm sure most LA purchasers make more than one visit before a decision is made.
They'll know you are serious by the interest you show and questions you ask!!
Good Luck GingerK ... and ENJOY your LA shopping experience as you move closer to the big decision!
