@Intellectsucks - you rock, keep it up!
Consider getting panniers or a basket for your bike instead of wearing a bag or backpack to cut down on the amount of sweat. Also a bike with gears will allow you to adjust your pace to reduce the amount of exertion and thus sweat.
Also about the Costco trip, consider pulling a bike trailer. If the trip is too far or dangerous Uber or Lyft are also an option. Remember the cost of a car includes tag, insurance, gas and ongoing maintenance. You could probably come up with a calculation to decide how much it would save you to skip the car. You're in a good position to see what life is like without the car before making the purchase as opposed to most who already own a car and have "wean off" it.
Great ideas there!
I think I'm going to intentionally postpone the vehicle purchase so I'm forced to use my bike. Uber/Lyft is very active in my area (one of the things I checked while at the new apt) so I think I can get away with it for now, but only when I have a long trip.
I scouted the area and there is a moderately-priced grocery store within easy biking distance. I'll use them for filling in the grocery gaps (some fruit/veggies) and there's also a farmer's market close by on the weekends so I'm hoping I can avoid the fancypants-facepunch grocery store.
I'm going to search for bike trailers as well. (helluva lot cheaper than a car) I may try to buy one here in Longmont before I move. My company is paying for my moving expenses and since the tax rate in CO is 2.9% vs. CA at 7.5 - 8.48%, purchasing here and getting a "free" ride to CA probably makes more sense. (of course I plan to check Craigslist first)
I'll look into the panniers as well. That would make packing my laptop and sack lunch a lot easier!
My bike is a Schwinn Trailway with 3/7 speed shifters. (just got it brand new on Craigslist - lady bought it for her son and he didn't like it. $350new - $100 my price) Her loss, my gain. So I think that will help with the pace and grinding, thus less-sweatiness...
Any thoughts on fenders/splash guards for commuter bikes? It rarely rains in Orange County so I may try to get away with no fenders for now, but I'll have to see after a couple of trips. I'm moving into my apt a week before my first work day, so I plan on testing the trip on my bike during my normal commuting hours to ensure I know what I'm doing.
As for a vehicle, my apartment comes with a covered garage, so I plan on looking for a project car and taking my time with working on it. I may use it for a while (if I need it) or I may just sell it and make a profit. My only concern is, I've been consulting for the last 18 months and I still have some side hustles going on which are mostly up in Los Angeles. I'm going to research the options for trains to see if I can bike to the station and take the train to my clients' offices.
Again, thanks everyone for the advice and encouragement! Moving from Longmont, CO to Irvine, CA is going to take some adjustment and of course ignoring the "status quo" in the OC. (ie - fancy cars, clown-like traveling, fancy houses, fancy food, fancy lifestyle), but the paycheck was just too good to turn down. *sigh*
