<human>: Can you summarize the given text in a few sentences?

Reddit, I live by the beautiful coast of southern California. Not close enough to walk but close enough to bike. Yesterday I got off my night shift at 8AM and decided to ride my bike down to Huntington Beach and take a dip. I've been to this exact beach about 100 times and I've always just left my stuff near other people and no one ever fucks with it.

Not today. I swam for about 30 minutes and decided to call it a day. I went back to the lifeguard tower where my stuff was, no stuff. I had a lot of my important things in that bag and that's the real fuck up here. My phone, my wallet, keys, shoes, shirt, glasses, prescription sunglasses. All told around $1000 of value. I was left with literally only the shorts I was wearing. I borrowed someone's phone and got someone to pick me up but not before getting a nice, painful sunburn.

Now I have vision insurance and spare glasses, I'll get those replaced for a minimal cost. My phone is just a phone and I didn't have any cash. The thieves used my card to buy some booze but I probably won't even have to pay for that.

Here's the real problem my bike was still locked up and I am fresh out of keys. I did some damage on the lock with borrowed bolt cutters but we managed to break them (they were shitty bolt butters). I worked on the lock with a hack saw until about 11 PM last night until I had to go to work again which I was a couple hours late to. I bought a new, thick lock (with borrowed money since I'm effectively broke) and put it on so that the bike wasn't just protected by a now compromised lock. Also, I haven't slept since 9 pm on Tuesday night besides when I  fell asleep at work for a couple hours
<bot>: all my shit got stolen and now I need to steal my own bike. Any tips on bike thievery would be greatly appreciated, I think I'm gonna buy an angle grinder.
